Then

mg-pgV = P

That is, you need to know your volume

the volume can be found if you know the cross-sectional area, for example, of a pool, and by measuring the change in water level.

then V = S * (H-h), where S is the area of the pool in square meters, H is the final water level in meters, h is the initial water level in meters
