"One zhang is equal to ten feet, one foot is equal to ten inches, the size is a fixed number, take the length of three feet as the sum, set it as one meter, one meter is equal to ten meters, one decimeter is equal to ten centimeters, one centimeter is equal to ten millimeters, one millimeter is equal to ten silk meters, one millimeter is equal to one hundred microns, although the silk meter micron seems very small now, many places may not be used, but set it down first, and when it can be used in the future, there is evidence to follow......"

On the morning of November 16th, in a courtyard in the Huanglong County Manufacturing Bureau, a newly made plaque was hung up, and the plaque was hung with three golden characters - "Weighing Instrument Hall", in a room of the Weighing Instrument Hall, Yan Liqiangzheng and Qian Su, as well as a craftsman from the Manufacturing Bureau, carefully put several standard weighing instruments newly created by the Manufacturing Bureau into the display cabinet of the Manufacturing Hall, as the future weighing instrument standards of the Manufacturing Bureau.

The new scales, made of the most expensive meteorite alloy that the manufacturing bureau could find, were strong, wear-resistant, and hard-to-break with swords, and as long as they were not thrown into the steel-making furnace and re-melted, they would be basically undamaged.

Looking at those rulers of different lengths, metal squares of different weights, and metal measuring cylinders that were full of metallic texture and heavy in his hands, Yan Liqiang's heart was filled with a strange feeling, to a certain extent, he was now creating the history of this world.

On the issue of weights and measures, he talked to Zhang Yourong when he was in the imperial capital, Zhang Yourong's views are consistent with Yan Liqiang, that is, the current weights and measures standards in this world, there are great defects, this defect is extremely unfavorable to the development of the way of the object, the simplest, take the length, the weights and measures of this world can generally be used only five, li, zhang, ruler, inch, minute, one mile is equal to 150 zhang, one zhang 10 feet, one foot 10 inches, one inch 10 minutes, the smallest length unit is minutes, and one minute is 3.333 mm, the size of the craftsman to make things can be defined by the most accurate points, but, the minimum error of about 3 mm is OK with the naked eye, manufacturing many supplies in life, building furniture, swords, armor and building houses, this error is nothing, and once it comes to more precise appliance manufacturing, the embarrassment and helplessness of the smallest length of weights and measures is reflected, the so-called precision, there is a lack of more objective standard measurement.

In view of this, Yan Liqiang introduced the set of length units he was familiar with in the manufacturing bureau in the past two days, and used the standard three feet to determine the base number of one meter, and then extended downward, and when extending to the concept of millimeters, Yan Liqiang also really invented a new length unit - silk meters, as an excess between millimeters and microns, so that craftsmen are more acceptable.

With this basic unit of length, then, the unit of area and volume is also determined in order, the area of one centimeter of length and width is one square centimeter, the volume of one centimeter of length, width and height is one cubic centimeter, and one cubic centimeter is equal to one milliliter of capacity, and one cubic meter is 1000 liters......

With this volume and volume, the traditional four units of measurement used by the craftsmen of the manufacturing bureau, the Hu Dou Shenghe, are dwarfed by the new set of measurement units.

With the weights and measures of volume and volume, Yan Liqiang redetermined the unit of measurement of weight with the weight of 1 kilogram of a liter of water at room temperature, 1 kilogram is equal to 1,000 grams, and 1 gram is equal to 1,000 milligrams.

Yan Liqiang was in the weighing instrument hall, holding the carefully made weighing instruments one by one, and told the leaders of the manufacturing bureau about the relationship and connection between the various weights and measures.

Putting down the one-liter standard metal measuring device in his hand, Yan Liqiang picked up another disc, pointed to the scale and words on the disc and said to everyone, " In addition to the previous scales, there is also a time measurement to be proposed, I know that everyone has been accustomed to using the Zi Chou Yin Mao Chen Si Wu Wei Shen Youxu Hai twelve earth branches to determine the twelve hours of the day, each hour is divided into eight quarters, but even if we can still divide the moment into two and a half quarters, but such a division is too crude, you must know that for a master, even if it is only half a quarter of time, it can already decide the life and death of a duel, or kill hundreds of people, this short half quarter of an hour can already give birth to countless life and death victories and defeats, we as craftsmen, how can we be so crude, want to keep improving, we must refine the timeAs a craftsman, there must be a belief in your heart, that is, between heaven and earth, all things can be measured......"

"Ahem, in fact, in addition to the hour and a half, we usually talk about time and other words, the shortest is actually a breath, and there is a moment, a cup of tea, a stick of incense, these are all ways to measure the length of time......" An old craftsman coughed and added in the crowd.

"Very good, you just said that a breath, a moment, a cup of tea, a stick of incense, are all units of measuring time, then let me ask you, how much time is a breath, a breath is a breath, how much breath is a quarter of an hour?" Yan Liqiang asked with a smile.

"I haven't counted this, but it's probably ...... About two or three hundred times, right?"

"Okay, so when you breathe 200 times in a quarter of an hour, and you say that a quarter of an hour is equal to 200 breaths, do you think that other people will agree with what you say?

"This ......," the old craftsman was speechless for a moment.

"Of course, the answer is different, because for different people, the time to breathe and breathe is also different, children and infirm people breathe for a short time, they breathe rapidly, and strong people breathe for a long time, especially for many cultivators, the time of their breath is already equivalent to a dozen breaths of ordinary people, not to mention too far, in this room, my breath is also different from everyone's breath, basically many of you breathe more than six times, I only breathe once, so the ten breaths you say are different from the ten breaths I say, you say that a quarter of an hour is equal to two hundred breaths, and for me, a quarter of an hour is just a few dozen breaths, the sameFor a cup of tea, some people drink for a long time, some people drink for a short time, the time of a cup of tea is different for different people, a stick of incense is the same, and the time required for different incense to burn is also different, so there must be a more objective and accurate standard in the measurement of time......"

"In the future, in the manufacturing bureau, the day is still twelve hours, but each hour is divided into two hours, for example, the sub-hour, then it can be divided into two hours, at the same time, one hour is equal to sixty minutes, equal to four quarters, each moment is equal to fifteen minutes, every minute, and sixty seconds, how long is a second, that is, we can follow me to try it, one, two, three, four, about one second, if it is more accurateThis second is the time it takes for a bird's egg to fall from a five-meter-high branch, and we don't have the tools to accurately measure a second, but not having it now does not mean that it will not have it in the future. If anyone can make a timekeeping instrument measured in seconds, I will reward him with ten thousand taels of silver............"

10,000 taels of silver? Yan Liqiang's words caused a commotion among a bunch of craftsmen, and the eyes of many craftsmen suddenly lit up......

"In the future, in the manufacturing camp, to form rules, when everyone uses the measurement, we must use the unit of these scales displayed in the weighing hall as the standard, to make things, we must be able to use these new weights and measures to accurately say how long, heavy, how big, the time required for each process must be at least accurate to the minute, for example, when making lacquer, the time interval between the second lacquer and the first lacquer, it must be accurate to the minute, determine how many minutes is the best, and not just rely on experience, the size of many delicate tools and utensils should be accurate to millimeters, even silk meters, and the weight of metalworking appliances and tools should be accurate to grams, the specific accuracy error, you discuss and decide!"

"Some people may not know why I emphasize these in the manufacturing bureau, then I will tell you, in just these few days, our manufacturing bureau has received more than 30 orders for four-wheeled carriages, 1780,000 taels of silver has been accounted for, we are the first to collect the money, then delivery, these recorded silver, half of the money is yours, this is just an order from Pingxi County, there will be more orders in the future, the carriages we manufacture will definitely make people red, and there will be imitations in the future, everyone wants to live a good life in the future, want to get a large amount of dividends every year, must have excellent craftsmanship, others do not have, we want to have, others have, We have to be better than them, if we want to do this, then we must have the spirit of excellence, what is excellence, then we have to measure these things......" Yan Liqiang turned around and pointed to the tools and standard scales displayed in the room.

"Don't worry, Lord Guardian, we know how to do it!"

Seeing that the craftsmen were nodding their heads and patting their chests, Yan Liqiang finally put his mind at ease, he turned his head to look at Qian Su, "Uncle Qian, I think the manufacturing bureau can first take out 50,000 taels of silver that we have entered the account in the past few days to share it with everyone, which is counted as a reward for everyone's hard work a few days ago, cheer everyone up, and let everyone feel what is going on with dividends according to shares, in the future, the manufacturing bureau will earn more, and everyone will share more, the rules I have set in the manufacturing bureau are one and the same, real money, rewards and punishments must be believed......"

"Okay, we can divide it today, so that everyone is happy and happy!" Qian Su, who understood Yan Liqiang's intentions, nodded and said.

In the afternoon, the silver division meeting began, and the top and bottom of the manufacturing bureau, from the craftsmen, the craftsmen, to the sergeants and laborers, were all boiling, because according to the shares, the entire manufacturing bureau, even the lowest level of labor, each had a share, and this share could be divided into 14 taels and 6 coins of silver, and those craftsmen and stewards who had 30 shares of shares were each given almost 400 taels of silver at once, and the most ordinary craftsmen and sergeants with 3 shares were also divided into more than 40 taels each, and many people were so excited that they shed tears with the silver flowers they had received in their hands。

Since Yan Liqiang came to the Manufacturing Bureau, in just a short period of time, the Manufacturing Bureau has been turned upside down all of a sudden, and the 50,000 taels of real money and silver have been reduced to a cent, which is more effective than anything else, and the morale of the entire Manufacturing Bureau has boiled like a volcano, and Yan Liqiang's lofty position in the minds of the people of the Manufacturing Bureau has also been established......
