If calculated according to the specific gravity of water, one liter is two kilograms. Because the specific gravity of water and oil is different, the specific gravity of oil is 0.9 and that of water is 1, so the weight of soybean oil is 1.8 kg.

Solution: According to the formula, mass = volume x density, and the density of soybean oil ρ= 900kg/m3.

Soybean oil quality = soybean oil density x soybean oil volume

= 900kg/m3 x 1 liter

= 900kg/m3 x0.00 1 m3

= 0.93kg =1.8kg. ..

That is, 1 liter of soybean oil is equal to 1.8 kg.

Extended data:

Modern "gold" has the following conversion to metric system according to local usage habits:

Chinese mainland 1 kg equals 500 grams (g).

Hong Kong and Macao 1 kg is about 605(g).

Taiwan Province province 1 kg is equal to 600g.

At present, Hong Kong law stipulates that one kilogram is equal to one hundredth of a load or sixteen taels, that is, 604.82 grams (g).

Table system commonly used in Taiwan Province market: 1 kg = 600g. But Jinmen and Mazu are adjacent to Fujian Province, so Taiwan Province Gold is not needed. The so-called "Jin" is 1 Jin = 500 grams.
