What Is This Tool?
This converter transforms pressure measurements from inch water (4°C), a unit suited for fine low-pressure readings, into kilogram-force per square centimeter, a legacy unit common in hydraulic and industrial settings.
How to Use This Tool?
-
Enter the pressure value in inch water (4°C) [inAq].
-
Select the target unit as kilogram-force per square centimeter (kgf/cm²).
-
Click convert to view the equivalent pressure in the chosen unit.
Key Features
-
Converts inch water (4°C) [inAq], a precise low-pressure unit, to kilogram-force/sq. cm, a non-SI pressure unit.
-
Ideal for translating measurements used in HVAC, laboratory testing, and hydraulic system specification.
-
Browser-based and user-friendly interface for quick pressure unit conversions.
-
Supports conversion between small-scale hydrostatic pressure and larger industrial pressure units.
Examples
-
10 inch water (4°C) equals 0.025399295 kilogram-force per square centimeter.
-
50 inch water (4°C) equals 0.126996475 kilogram-force per square centimeter.
Common Use Cases
-
Monitoring static and differential pressures in HVAC ducts and ventilation systems.
-
Testing low-pressure gas lines and burner manifolds in laboratory environments.
-
Specifying pressures in hydraulic systems and actuators in legacy engineering contexts.
-
Reading pressure drops across filters and clean-room equipment in industrial settings.
Tips & Best Practices
-
Use this tool for pressure values within low to moderate ranges for accurate interpretation.
-
Account for the non-SI nature of kilogram-force per square centimeter when interfacing with SI-based systems.
-
Apply the conversion to bridge precise measurements with industrial or regional documentation.
Limitations
-
Inch water (4°C) is intended for fine low-pressure readings and may be impractical for very high pressures.
-
Kilogram-force per square centimeter is a non-SI unit requiring caution in strictly SI unit contexts.
-
Conversion accuracy depends on compatible pressure ranges; extremely high pressures are not suitable.
Frequently Asked Questions
-
What does inch water (4°C) measure?
-
It measures hydrostatic pressure produced by a 1-inch column of pure water at 4 °C under standard gravity and is used for low-pressure measurements.
-
Why convert inch water to kilogram-force per square centimeter?
-
This conversion translates fine low-pressure readings into legacy units commonly used in hydraulic and industrial equipment specifications.
-
Is kilogram-force per square centimeter an SI unit?
-
No, it is a non-SI unit often used in older or regional engineering documents and industrial equipment ratings.
Key Terminology
-
Inch water (4°C) [inAq]
-
A pressure unit defined by the hydrostatic pressure from a 1-inch column of pure water at 4 °C, used for sensitive low-pressure measurements.
-
Kilogram-force per square centimeter (kgf/cm²)
-
A non-SI pressure unit representing the force of one kilogram-force applied uniformly over an area of one square centimeter, commonly used in legacy engineering applications.
