What Is This Tool?
This converter transforms pressure values from foot water (60°F), a unit representing hydrostatic pressure of a one-foot water column at 60°F, to centimeter water (4°C), which measures pressure from a one-centimeter water column at 4°C. It is useful for professionals working in fields like HVAC, medical respiratory care, and laboratory pressure measurements.

Tips & Best Practices
-
Ensure the correct temperature reference for each unit is considered during interpretation
-
Use this converter for low-pressure measurements where water density assumptions apply
-
Verify unit selections carefully to avoid incorrect conversions
-
Supplement this tool with SI unit conversions if required for strict instrumentation compliance
Limitations
-
Conversion assumes standard gravity and specific water temperatures which affect accuracy
-
Centimeter water (4°C) is a non-SI unit and may not be suitable for high-precision instrument standards
-
Variations in environmental conditions can lead to slight discrepancies in pressure values
Frequently Asked Questions
-
What does 1 foot water (60°F) represent?
-
It is the pressure exerted by a one-foot column of pure water at 60°F under standard gravity.
-
Why use centimeter water (4°C) for pressure measurements?
-
Because it reflects hydrostatic pressure at the temperature of maximum water density, making it suitable for medical and laboratory applications.
-
Can I use this conversion for all pressure measurements?
-
This conversion is intended for low-pressure hydrostatic measurements and may not be appropriate when temperature or gravity conditions vary.
Key Terminology
-
Foot Water (60°F) [ftAq]
-
A pressure unit based on the hydrostatic pressure of a 1-foot column of water at 60°F under standard gravity, used for low-pressure measurements.
-
Centimeter Water (4°C)
-
A non-SI pressure unit defined by the hydrostatic pressure from a 1-centimeter column of water at 4°C, common in medical and laboratory pressure readings.
-
Hydrostatic Pressure
-
Pressure exerted by a fluid at equilibrium due to the force of gravity acting on the fluid column.
