# Unit Weight of Water

Unit weight of water, also called specific weight of water, is a measure of the weight of water per unit volume. It is typically expressed in units of force per unit volume, such as pounds per cubic foot (lb/ft³) in the Imperial system or newtons per cubic meter (N/m³) in the metric system. It's worth noting that the unit weight of water can vary slightly with changes in temperature and pressure, but these values are commonly used for practical calculations in engineering and science.
