Another folk method is to use "liter" as the unit of measurement. One liter is one tenth of a barrel, and one liter is 1.5 kg 3/4 kg. In the past, people invented this method of measuring rice by volume without standard weights and measures, and it is still very useful now. There are many literary works that reveal that landlords and usurers cheat farmers by promoting (fighting) small and promoting (fighting) big. Reflected the exploitation system of feudal society.

According to Hanshu, one Hu is 2,000, the erhu weighs one or two, and one Hu weighs 1,200, or 62.5 Jin. Therefore, during the Qin and Han dynasties, a handful of millet weighed about half a stone, and a stone of millet accumulated about two sticks. (Note: A pair in Qin and Han Dynasties was16g, so a handful of millet weighed16kg).

According to the records of Qin and Han Dynasties, a liter of millet weighs twelve taels (about 190 ml of millet weighs about 160 g), and the specific gravity of this millet is about 0.85.

Extended data

The conversion relationship between L and other unit of volume is:

1l =1000ml = 0.001m3 =1m3 decimeter = 1000m3.

1L = 1dm * 1dm * 1dm = 10cm * 10cm * 65438+ 10cm

1 ml = 1 cm3 = 1 cm3

1 m3 = 1000 liter

One liter = 1000 ml, one gallon (USA) 3785.45438+01784 ml, one gallon (UK) 4546.38+088 ml.

One liter in Korea is about 1800 ml, and one liter in Japan is about 1803.9 ml.

Cross conversion: one liter ≈0.26 gallon (American system) and one liter ≈0.22 gallon (British system).
