What does one Torr represent?

One Torr is a unit of pressure equal to 1/760 of a standard atmosphere, commonly used to measure low pressures and vacua.

What is foot water (4°C)?

Foot water (4°C) is a pressure unit based on the hydrostatic pressure exerted by a one-foot column of water at 4°C.

Why convert Torr to foot water (4°C)?

Converting Torr to foot water (4°C) is useful to relate vacuum or low pressure measurements to hydraulic pressure expressed as water column height in fluid mechanics.

Includes exact conversion rate for precise calculation
Useful for scientific, industrial, and hydraulic applications
Browser-based and easy to operate

Examples

10 Torr converts to 0.446046372 foot water (4°C)
50 Torr converts to 2.23023186 foot water (4°C)

Common Use Cases

Measuring vacuum levels in laboratory and industrial vacuum systems
Specifying pressure head for pumps and water-distribution systems
Interpreting gauge readings in HVAC or fluid instrumentation
Assessing static head in groundwater and well measurements

Tips & Best Practices

Ensure temperature is close to 4°C when relating to foot water pressure
Understand that Torr measures absolute or gauge pressure, while foot water reflects hydrostatic pressure head
Use the conversion in applicable scientific or engineering contexts involving low pressure and hydraulic head

Limitations

Pressure equivalence can vary with temperature or fluid density changes from 4°C water baseline
Torr and foot water represent different types of pressure; correct reference conditions are required for proper use
