The imperial, a traditional system of units, is forcibly applied to modern science, which will greatly increase the difficulty of learning and use, increase the probability of error, and even cause economic losses.

What about the modern metric system in reverse?

As a scientific unit system, it is designed to use the decimal system as much as possible to facilitate the conversion of different units, and for large numbers, there is also scientific notation assistance.

1 km = 1000 meters.

1 meter = 10 decimeters = 100 centimeters = 1000 mm.

1 square meter = 100 square decimeters = 10,000 square centimeters.

1 cubic meter = 1000 liters = 1000000 milliliters = 1 ton of water.

1 cubic centimeter = 1 ml = 1 gram of water.

This combination of length, area, and volume units combined with conversion, which can still make OCD feel extremely comfortable, is forcibly formulated by the decimal system in combination with modern natural science.

At the same time, nautical miles and knots, also belong to the metric system, not the imperial system.

The Earth is a sphere with a circumference of 360 degrees and 1 degree of 60 minutes.

The true meaning of knot 1 is that a ship moves at an angle of 1 minute on the surface of the sphere, the earth, in the space of 1 hour.

The length of this 1-minute arc is 1 nautical mile.

The nautical mile is a nautical unit, which belongs to a different system from the other metric systems, so the data is not good to convert.

For the future development of mathematics, architecture, engineering, and science, it is necessary to avoid increasing the difficulty of ordinary people in learning because of the basic knowledge of the unit.

Mu Feng and the ship girls decisively chose the public system as the official unit system of the headquarters.

In the future, all aspects of education, scientific research, engineering, commerce, culture, etc., all use metric units.

Since the nautical mile is based on the earth's scale, which does not correspond to the surface scale of the planet, the shipwives habitually use the converted kilometer number.

Therefore, in the future, in the industry and the people, nautical miles and knots are no longer used, and kilometers and corresponding kilometers per hour and meters per second are used as units.

At the same time, the network root server room of the Shuangyue Islands is about to be completed, and the submarine fiber optic cable extending from Wanling Island to other islands is being laid in full force.

The construction of wireless signal towers and radio and television towers in various military ports has also begun, and the network coverage can be completed after the laying of submarine optical cables.

At the same time, the two-shift policy for factory workers, which had been completed in the old liberated areas, had been extended to the new liberated areas, and fixed public holidays had begun to be promoted.

However, this first public holiday is not completely free, and classes must be gathered.

Recognize the most basic hundreds of commonly used Chinese characters and the Chinese characters that need to be used in our factory.

When Mu Feng had breakfast, he browsed the construction and reform trends of the entire headquarters through the system and data link.

I learned about the things I needed to know, and I took a look at the things I needed to do myself.

Then, together with Yuanwang 7, I took a plane back to Xingang and went to the scientific research center together.

The two sisters, Neptune and Sirius, temporarily stayed in New Town, the capital of the Bilunar Islands, to be in charge of publicity, information, and network construction.

So at this time, there was no one in the research center.

Mu Feng accompanied Yuanwang No. 7, sat on the sofa for a while, chatted for a while, and then got up together and came to the front of the scientific research equipment.

Mu Feng swiped the screen with his hand, looking at a series of recently completed scientific research projects on it.

In each of these projects, I actually received a system notification when I completed each project.

It's just that when I was notified, it all appeared separately one by one, and I didn't pay much attention to it at the time.

Looking at them lined up now, I found that the number was really quite a lot, and I couldn't help but feel a little distressed and said:

"Seventh sister, this time, I have really worked hard for you."

Yuanwang No. 7 smiled and shook his head and said:

"Actually, it's okay, most of them are the integration of existing mature technologies, the workload is not large, and a lot of scientific research is required, in fact, there are only a few.

"So far, what we have been missing before, the traditional equipment sector, has basically been completed, and we now have to determine the next scientific research plan.

"Here, according to my train of thought, there are roughly three directions.

"First, further upgrade new equipment, such as the next generation of anti-ship missiles, anti-ship ballistic missiles, variable-cycle engines, quantum, lidar, new fire explosives, and so on.

"Second, design a new generation of capital ships, and let the existing capital ships be upgraded through hull remodeling, such as the next generation of destroyers, all-round ships, next-generation aircraft carriers, and so on.

"Third, complete the missing categories of modern equipment and ships, such as large strategic bombers, strategic missile nuclear submarines, rockets, satellites and other aerospace equipment, nuclear weapons, and so on."

Mu Feng listened carefully to the explanation of Yuanwang No. 7 and began to use the elimination method:

"Our conventional is already ahead of the enemy, so missiles, aircraft, radars, and explosives do not need to be upgraded in a short period of time.

"And then for the same reason, the existing capital ships do not need to be upgraded in a short time, and strategic bombers are not needed for the time being.

"I believe that we should now gradually complete the missing modern equipment, including nuclear weapons, strategic missile submarines, as well as rockets and satellites."

Yuanwang No. 7 squinted his eyes and said:

"Strategic missile nuclear submarines, carrying strategic missiles, and strategic missiles carrying nuclear weapons. Rockets for launching satellites and strategic missile technology actually have the same goal.

"Therefore, the research and development of strategic missile nuclear submarines is equivalent to the development of nuclear-powered submarine technology, strategic missile technology, and nuclear weapons technology, which can be completed through one project."

Mu Feng nodded seriously and said:

"So, my suggestion is that the next scientific research program, the Type 096 strategic missile nuclear submarine."

Yuanwang 7 did not speak, and found the existing scientific research plan of 096 in the system:

"Attack nuclear submarines, and strategic missile nuclear submarines, many times are twin sisters, and the vast majority of technologies are similar on the two submarines of the same generation.

"Most countries first develop attack nuclear submarines, and then use the technology to design submarines that can carry strategic missiles, which become strategic missile nuclear submarines.

"On the contrary, the strategic missiles themselves, and the nuclear weapons they carry, need to be tackled separately.

"So, my opinion is that two programs should be carried out at the same time, and the hulls of nuclear submarines of two sizes will be designed at the same time."

Mu Feng understood the meaning of Yuanwang 7, the two submarines are in pairs, and the scientific research progress of this one will be advanced, and the other will also move forward, which can save a lot of time.

So Mu Feng nodded and agreed, and opened the scientific research plans of 095 and 096 at the same time:

"I understand, let's determine the specific design goals......"
