Frequently Asked Questions
-
What does pound-force per square inch measure?
-
Pound-force per square inch (psi) measures pressure as the amount of force applied in pounds on an area of one square inch.
-
What is centimeter mercury (0°C) in pressure measurements?
-
Centimeter mercury (0°C) is a pressure unit defined by the hydrostatic pressure from a 1-centimeter mercury column at 0°C under standard gravity.
-
Why convert psi to centimeter mercury (0°C)?
-
Converting psi to centimeter mercury (0°C) helps translate pressure readings commonly used in mechanical systems into manometric units used in laboratory and scientific settings.
Key Terminology
-
Pound-force per square inch (psi)
-
An imperial pressure unit representing one pound-force applied to an area of one square inch, commonly used in engineering and everyday contexts.
-
Centimeter mercury (0°C)
-
A pressure unit based on the hydrostatic pressure exerted by a one-centimeter column of mercury at zero degrees Celsius under standard gravity.
-
Manometric unit
-
A type of pressure measurement based on the height of a column of fluid, such as mercury, used in pressure sensing and calibration.
