① The densities of different oils are slightly different.
② If it is 20 liters of water, it is exactly 40 kilograms, but the density of oil is smaller than that of water. 1 liter of water is about 1 kg, while soybean oil on the market is about 0.92 kg per liter. 1 kg is 2 kg.
Unit of volume transformation
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
