What Is This Tool?
This tool converts pressure measurements from pound-force per square foot, a US customary unit used in engineering, to centimeter mercury (0°C), a manometric unit based on mercury column pressure used in labs and calibration.
How to Use This Tool?
-
Enter the pressure value in pound-force per square foot.
-

Examples
-
10 pound-force/square foot converts to approximately 0.359132469 centimeter mercury (0°C).
-
50 pound-force/square foot converts to approximately 1.795662345 centimeter mercury (0°C).
Common Use Cases
-
Determining building floor live loads and roof snow loads using pound-force/square foot and converting for scientific measurement.
-
Calibrating pressure sensors and vacuum gauges that use mercury-based units.
-
Comparing wind pressures on structures with manometric pressure readings.
-
Reporting small pressure differences in physics and engineering experiments.
Tips & Best Practices
-
Always verify the measurement context before converting between these units.
-
Remember that the conversion assumes standard gravity and mercury density at 0°C.
-
Use this tool mainly for small pressure differences and calibration purposes.
-
Consider environmental factors such as temperature or local gravity for precision tasks.
Limitations
-
Pound-force/square foot is typically for large-scale structural surface loads, while centimeter mercury is common for precise laboratory pressures.
-
Temperature or gravity variations can slightly affect mercury column pressure and therefore the conversion accuracy.
-
The conversion assumes ideal conditions that may not reflect all real-world measurement environments.
Frequently Asked Questions
-
What does pound-force per square foot measure?
-
It measures pressure as one pound-force uniformly distributed over an area of one square foot, used mainly in US customary engineering contexts.
-
What is centimeter mercury (0°C)?
-
Centimeter mercury (0°C) is a pressure unit representing the pressure exerted by a 1 cm column of mercury at 0°C under standard gravity.
-
Why convert pound-force/square foot to centimeter mercury (0°C)?
-
Conversions allow comparison and calibration between US customary pressures and precision laboratory measurements using mercury columns.
