There is no saying that 1L is how many kilograms. liter is a unit of volume, while kilogram is a unit of weight, so they cannot be transformed into each other. The relative mass of 1L varies according to the density of different substances. For example, the density of water is 1 g per ml, and 1 l is equal to 1000 ml, so 1000 ml of water is equal to 1000 g.
Volume refers to the volume of objects that a container can hold. The volume units of solids and gases are the same as those in unit of volume, expressed in cubic meters, cubic decimeters and cubic centimeters, while the volume units of liquids are generally expressed in liters and milliliters. The unit of volume is sometimes commonly used in unit of volume, because the largest unit of volume is "liter", so when calculating the volume of larger objects, the general unit of volume still uses "cubic meter".
Unit conversion
1,1l (l) = 0.001m3 (m? )
2.1l (l) =1cubic decimeter (dm? )
3,1l (l) =1000 cubic centimeters (cm? )
4. 1 ml =1cm3 (cm? ）＝ 1cc
5. 1 m3 (m? ) =1000 l (l)
6. One liter (L) =1000 mL.
7. 10000 milliliters (ml) =1000 cubic centimeters (cm? ) =1cubic decimeter (dm? )
8. 1 mL liquid water =1cubic centimeter (cm? ) liquid water
9. 1 liter (L)= 1000 ml = 0.001m3 (m? ) =1cubic decimeter (dm? ) =1000 cubic centimeter (cm? )
