Tips & Best Practices
-
Verify that input values represent pressure in gram-force per square centimeter correctly
-
Use the converted values for low-pressure applications requiring fine resolution
-
Consider the temperature dependency of inch water (4°C) when using results in field applications
-
Apply this conversion for consistency between legacy and modern pressure data
-
Perform conversions under standard gravity and temperature assumptions for accuracy
Limitations
-
Gram-force/sq. centimeter is not an SI unit and depends on local gravitational acceleration, which can vary
-
Inch water (4°C) assumes water at exactly 4 °C and standard gravity, affecting precision if conditions differ
-
Conversion may slightly diverge from exact values if reference states are not standard
Frequently Asked Questions
-
Why convert gram-force/sq. centimeter to inch water (4°C)?
-
This conversion enables translating older gravitational force–based pressure measurements to a modern hydrostatic scale used in sensitive low-pressure applications like HVAC and laboratory testing.
-
Is gram-force/sq. centimeter an SI unit?
-
No, gram-force per square centimeter is a non-SI unit based on gravitational force and used mainly in legacy and specialized contexts.
-
What conditions affect the accuracy of inch water (4°C)?
-
Inch water pressure units depend on water temperature precisely being 4 °C and standard gravity, so deviations can affect measurement accuracy.
Key Terminology
-
Gram-force/sq. centimeter
-
A pressure unit defining force of one gram-force applied per square centimeter, non-SI, based on gravitational force.
-
Inch water (4°C) [inAq]
-
A unit of pressure representing the hydrostatic pressure of a one-inch column of water at 4 °C under standard gravity.
