L is unit of volume and Jin is the unit of weight. They are different. But according to weight = density x volume, 1 liter = 1000 cubic centimeter. Is the density of water 1g/cm? , so 1 weight of water =1x1000 =1000g. Because 1 kg = 500g,1000g = 2kg.

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

1l = 1 000 ml = 0.001cubic meter =1cubic decimeter = 1000 cubic centimeter.

1L = 1dm * 1dm * 1dm = 10cm * 10cm * 10cm .

1 ml = 1 cm3 = 1 ml.

1 m3 = 1000 liter.
