What Is This Tool?
This tool converts pressure measurements from Inch Water (60°F) [inAq], a unit representing hydrostatic pressure of a 1-inch water column at 60 °F, to Dyne per square centimeter (dyne/cm²), a CGS unit of pressure equal to one dyne applied over a square centimeter.

Expressing small pressures in CGS units for physics or legacy scientific literature
-
Reporting low gas or vacuum pressures in laboratory experiments
-
Comparing data in scientific fields such as astrophysics or plasma physics that use CGS units
Tips & Best Practices
-
Confirm that measurements using inch water are at 60°F due to temperature dependence
-
Use the conversion factor carefully when dealing with very small pressure values
-
Convert to pascals if modern SI compatibility is needed after converting to dyne/cm²
-
Validate pressure readings from different measurement systems before comparisons
Limitations
-
Inch water unit depends on water temperature, with 60°F assumed for conversion
-
Dyne/square centimeter is uncommon in contemporary SI-based systems and might require further conversion
-
Converting very small pressure values may introduce noticeable approximation errors
Frequently Asked Questions
-
Why is the inch water unit specified at 60°F?
-
Because water density changes with temperature, specifying 60°F ensures the pressure measurement corresponds to a consistent hydrostatic pressure value.
-
What is a dyne per square centimeter used for?
-
It is used to express small pressures or mechanical stresses in physics and legacy scientific contexts that employ CGS units.
-
Can I use this conversion for modern SI measurements?
-
While dyne/cm² can be converted, it is less common in modern SI units, so additional conversion to pascals may be necessary.
Key Terminology
-
Inch Water (60°F) [inAq]
-
A pressure unit reflecting the hydrostatic pressure from a 1-inch column of water at 60 °F, used for measuring small pressure differences.
-
Dyne per square centimeter
-
A CGS pressure unit equal to one dyne of force applied uniformly across one square centimeter, also known as barye.
-
Hydrostatic Pressure
-
The pressure exerted by a fluid due to the force of gravity acting on it.
