Why are different temperatures specified for the foot and inch water units?

The foot water is defined at 60°F (15.556°C) while inch water is defined at 4°C; these temperature differences affect water density and thus the pressure each unit represents.

Can I use this converter for pressures in gases or other fluids?

This conversion is specifically for hydrostatic pressure units based on water columns and is not suitable for dynamic pressures or fluids other than water.

What is the conversion rate between foot water (60°F) and inch water (4°C)?

1 foot water (60°F) equals approximately 11.9884857196 inch water (4°C).

Key Terminology

Foot water (60°F) [ftAq]: A hydrostatic pressure unit defined by a 1-foot column of pure water at 60°F under standard gravity, used primarily for low-pressure and head-related measurements.
Inch water (4°C) [inAq]: A small pressure unit equal to the pressure exerted by a 1-inch column of pure water at 4°C under standard gravity, useful for precise low-pressure measurements.
Hydrostatic Pressure: The pressure exerted by a fluid at equilibrium due to the force of gravity acting on it.
