Why is inch water specified at 60°F?

Because the density of water changes with temperature, inch water pressure is temperature-dependent and is specified at 60°F to ensure consistent readings.

What is pound-force per square foot used for?

It is a pressure unit commonly used in US customary engineering to quantify surface loads such as building live loads, snow loads, and wind pressures.

Can this tool convert very small pressure differences accurately?

The conversion is suitable for general use, but pound-force per square foot may be less precise for very small pressure differences compared to inch water.

Examples

2 Inch water (60°F) equals 10.3943882218 Pound-force per square foot
0.5 Inch water (60°F) equals 2.59859705545 Pound-force per square foot

Common Use Cases

Measuring duct and filter pressure drops in HVAC systems
Specifying low residential gas pressures and regulator settings
Assessing manometer readings and differential pressure sensors in ventilation
Defining floor live loads and roof snow loads in structural engineering
Evaluating wind pressure on building exteriors for code compliance
Calculating distributed loads on beams and retaining walls in US customary units

Tips & Best Practices

Ensure the inch water pressure measurement is taken at the specified 60°F temperature
Use pound-force per square foot for larger scale engineering pressure assessments
Confirm units before converting to maintain consistent engineering data
Apply this conversion when translating HVAC and gas pressure measurements to structural load requirements

Limitations

Inch water pressure values vary with temperature due to water density changes, so accuracy depends on the 60°F reference
Pound-force per square foot is better suited for larger scale pressures and may not be precise for minimal pressure differences
Conversion uses standard gravity assumptions and does not adjust for local gravitational variations
