What is the metric units for liquid volum?

Answer 1

The cubic meter is the metric unit of volume.

Cubic meter is the SI unit of volume. It makes no difference whether the volume is occupied by a solid, a liquid, a gas, or a mixture of them, or is empty.

Because of subtle differences in the way the density of water is defined [ρ = 1 g/cc at water's greatest density--or at 4°C--(there is a slight difference)], there is a non-unity conversion between liters & cu m:

1 m3 = 999.973 liter (at 20 degree Celsius)

A cm3, a CC, or cubic centimeter is 0.999973 ml or milliliter

Answer 2

The official metric unit for liquid volume is the cubic meter. However, the liter and milliliter are also commonly used. [ 1.0 cubic meter = 1000 L ]. A liter corresponds to 1.057 quarts.
