Gumu:
In ancient times, people called taking two steps "a double step", and the distance was about 5 feet. As we all know, every 1 foot is about 1/3 meters. In the past, old people often said, "It is sixteen long and fifteen wide", which is exactly one acre of land when converted into the length of two steps.
As a matter of fact, the unit of measurement "mu" has been defined as the saying that it will be eliminated as early as 30 years ago, but China is a vast rural area, and many people are used to it, and it is still in use today. With the gradual integration of national measurement units with international standards, more and more places will use "hectares" in the future. Remember, 1 hectare is 1 10,000 square meters.
At present, the official unit of area measurement in the world is hectare, and the square area with a side length of 100 meters is 1 hectare. And it is stipulated that 1 hectare is equal to 15 mu of land, so after conversion, 1 mu of land is equal to 666.67 square meters, about 60 meters long and about 10 meters wide. Nowadays, vegetable greenhouses are popular in many rural areas, and the area of many standard greenhouses is about one acre.
For example. A standard basketball court is 28 meters long and 15 meters wide, which is 420 square meters. The area of an acre of land is about three times that of half a basketball court, which can be intuitively understood.
