## What is the weight per unit volume of water?

The usual unit of measurement for the density of water is gram per milliliter (1 g/ml) or 1 gram per cubic centimeter (1 g/cm3). In fact, the exact density of water is not actually 1 g/ml, but slightly less (very, very slightly less), at 0.

What is the unit weight of water in n m3? water has a specific gravity of 9810 N/m3. The specific gravity of a liquid, denoted SG, is defined as the ratio of the density of a liquid to the density of water at a certain temperature.

### How do you calculate unit weight of water?

In short, 1 mL (milliliter) of water has a mass of 1 g, so 1 liter has a mass of 1 kg. You can use this fact to calculate the mass of water from any volume: for example, 450 ml is 450 g, and 1.35 liters is 1.35 kg.
