The volume and weight conversion formulas of different substances are different. Taking water as an example, 1 liter is equal to 1kg.

The density of water is 1. 1L of water is converted into milliliters as 1000ml. One liter of water = two pounds = one kilogram. According to the formula M=pV, the density of water is 1g/ml, and the volume is 1L=1000ml. Substituting into the formula, M=1×1000=1000g=1KG (kilogram) has a density of 1. This is artificially set, but it is not directly defined. The density of water is 1 because the substance water is used as a reference when defining the mass unit.

Liter is a unit of volume, and kilogram is a unit of mass. The units are different, so direct conversion cannot be performed. But it can be calculated by density. The calculation formula is: mass = density times volume. For example, if the volume of water is 1 liter and the density is 1000kg per cubic meter, then the mass of water is calculated as follows: According to the conversion formula, 1L is equal to 0.001 cubic meter.

Introduction to unit conversion

1. 1 kilogram = 2 pounds (city pound) = 1000g.

2. 1 cubic decimeter = 1,000 cubic centimeters = 1,000,000 cubic millimeters = 1 liter = 1,000 milliliters = 0.061 cubic inches.

3. 1 cubic centimeter = 1000 cubic millimeters = 1 milliliter = 0.000061 cubic inches.

4. 1 cubic meter = 1,000 cubic decimeters = 1,000,000 cubic centimeters = 1000000000 cubic millimeters = 0.353 cubic feet = 1.3079 cubic yards.

5. 1 cubic inch = 0.016387 cubic decimeter = 16.387 cubic centimeter = 16387 cubic millimeter.

6. 1 cubic foot = 28.3 cubic decimeter = 28,300 cubic centimeters = 28,300,000 cubic millimeters.

7. 1 cubic yard = 27 cubic feet = 0.7646 cubic meters = 164.6 cubic decimeters = 164,600 cubic centimeters = 164,600,000 cubic millimeters.

8. 1 cubic foot = 31.143 bushels (UK) = 32.143 bushels (US).
