What Is This Tool?
This tool enables users to convert pressure values from centimeter mercury (0°C), a manometric unit, to poundal per square foot, a unit from the foot–pound–second (FPS) system. It assists in translating pressure readings between SI/manometric standards and legacy FPS units for various scientific and engineering applications.
How to Use This Tool?
-
Enter the pressure value in centimeter mercury (0°C) into the input field
-
Select 'centimeter mercury (0°C)' as the input unit
-
Choose 'poundal/square foot' as the output unit
-
Initiate the conversion to obtain the pressure in poundal/square foot
-
Review and apply the result according to your measurement or calculation needs
Key Features
-
Converts pressure values between centimeter mercury (0°C) and poundal/square foot units
-
Supports laboratory, engineering, and educational pressure measurement needs
-
Provides a simple interface for quick and accurate unit translation
-
Based on established conversion rates derived from physical definitions
-

Examples
-
2 cmHg (0°C) converts to approximately 1791.764954071 poundal/square foot
-
0.5 cmHg (0°C) converts to approximately 447.94123851775 poundal/square foot
Common Use Cases
-
Interpreting pressure readings from laboratory manometers and barometers using mercury columns
-
Calibrating and specifying pressure sensors or vacuum gauges in experimental setups
-

Tips & Best Practices
-
Ensure unit consistency when combining measurements across SI and FPS systems
-
Consider environmental influences such as temperature on mercury pressure readings
-
Use this conversion to translate legacy data for modern analysis
-
Check for unit system compatibility in engineering calculations and reporting
-
Apply conversion results carefully when precise pressure readings are critical
Limitations
-
Conversion precision can be affected by rounding and differences between SI and FPS systems
-
Poundal/square foot is less commonly used in contemporary applications
-
Environmental factors may impact the accuracy of mercury-based pressure measurements
Frequently Asked Questions
-
What does centimeter mercury (0°C) represent?
-
It is a manometric pressure unit equal to the pressure exerted by a 1-centimetre mercury column at 0°C under standard gravity.
-
Why convert to poundal/square foot?
-
It helps express pressure values in the FPS system, useful for legacy engineering calculations and certain educational contexts.
-
Are there any challenges when converting these units?
-
Yes, conversion accuracy may be reduced due to rounding and the fundamental differences between SI and FPS units.
Key Terminology
-
Centimeter mercury (0°C)
-
A manometric unit of pressure defined by the pressure from a mercury column 1 cm high at 0°C under standard gravity.
-
Poundal/square foot
-
A pressure unit in the FPS system representing one poundal of force over one square foot of area.
-
Manometric unit
-
A pressure measurement based on the height of a column of fluid, such as mercury, in a manometer.
