If it is water, because1l =1000 UML; And 1 ml of water is 1 g, then 1 liter of water is 1000 g, that is 1 kg, that is, 2 kg.
Another folk method is to use "liter" as the unit of measurement. A liter is one tenth of a barrel, and a liter of rice is 4000 grams, which is 8 kilograms (16 = 1 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.
Extended data:
L, unit of volume.
L is expressed as L in the international system of units, and its secondary unit is mL. 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
