What is the technical atmosphere (at) unit?

It is a non-SI pressure unit defined as one kilogram-force per square centimetre, equal to 98,066.5 pascals and approximately 0.96784 standard atmospheres.

Why is inch water measured at 60°F?

Because water density varies with temperature, inch water pressure is specified at 60°F to maintain consistency in pressure measurements.

When should I use this converter?

Use it to convert legacy industrial pressure values expressed in technical atmospheres to units suitable for low pressure measurements typical in HVAC and ventilation studies.

What Is This Tool?

This converter transforms pressure measurements from the technical atmosphere unit (at), historically used in industrial contexts, to inch water at 60°F (inAq), commonly applied in HVAC and low pressure assessments.

How to Use This Tool?

Enter the pressure value in atmosphere technical (at)
Select atmosphere technical (at) as the input unit
Choose inch water (60°F) [inAq] as the output unit
Click convert to see the equivalent pressure value

Key Features

Converts technical atmosphere to inch water (60°F) pressure units
Supports legacy industrial pressure data interpretation
Browser-based and user-friendly interface
Ideal for HVAC, gas service, and cleanroom pressure conversions

Examples

2 atmosphere technical (at) converts to approximately 788.18 inch water (60°F)
0.5 atmosphere technical (at) converts to approximately 197.04 inch water (60°F)

Common Use Cases

Interpreting historical pressure data from boilers and hydraulic systems
Measuring duct and filter pressure drops in HVAC setups
Specifying low residential gas pressures for regulation
Operating manometers and sensors for ventilation control

Tips & Best Practices

Ensure pressure values are in atmosphere technical (at) before conversion
Verify the temperature context since inch water depends on water density at 60°F
Use this tool to reconcile legacy and modern pressure measurement units accurately

Limitations

Inch water unit accuracy depends on water temperature fixed at 60°F
Atmosphere technical is a non-SI unit and may require careful conversion when used with modern measurements
