The analysis is as follows:
1, l is unit of volume? 1 liter is equal to 1000 ml; Jin is the unit of weight 1 Jin is equal to 500 grams.
2. If it is a liter of water, 1 liter of water = 1 kg =2 kg (city kg);
If the density of oil, wine, etc. is smaller than that of water, then 1 liter oil < 2 kg;
If it is salt water, milk, etc., it is denser than water, and the opposite is true.
