The milliliter (ml) is unit of volume, and the gram (g) is the unit of mass. There is a conversion relationship between volume and mass: m=ρV, where ρ is the density. If the density is known, the mass can be calculated from the volume.

Example: It is known that the density of water is 1g/cm? That is, the volume of 1 gram of water is 1 cubic centimeter. 1cm? = 1ml, according to the formula: mass = volume * density, then the mass of 100ml water = 100cm? * 1g/cm? = 100g。

Extended data

Common weight unit conversion:

1, 1 ton = 1000 kg? 1 ton =1000000g

Ton: Ton is a unit of weight, and one ton in metric system is equal to 1000 kg: a unit for calculating the volume of a ship, and one ton is equal to 2.83 cubic meters (or 100 cubic feet).

2. 1 kg =1000g? 500g = 1 kg

Kilogram: gram (symbol kg or ㎏) is the basic unit for measuring quality in the international system of units, and kilogram is also one of the most commonly used basic units in daily life.

3. 1 kg = 1 kg? 1 kg =2 kg

The kilogram, or kilogram (symbol kg or ㎏) is the basic unit for measuring quality in the international system of units, and the kilogram is also one of the most commonly used basic units in daily life.
