Enter the air pressure, water pressure, and the conversion factor into the calculator to determine the missing variable.
Air Pressure to Water Pressure Formula
The following formula is used to calculate the water pressure from air pressure using a conversion factor.
P_w = P_a * C_f
Variables:
- Pw is the water pressure in psi
- Pa is the air pressure in psi
- Cf is the conversion factor (typically 0.433)
To calculate the water pressure, multiply the air pressure by the conversion factor.
