Value

From

Pressure is force per unit area. Different fields use different units: tyres in PSI, weather in mbar or hPa, science in Pascals, diving in bar or atm. Converting between them is critical for safety in pneumatics and medicine.

P	Pressure	various	—
psi	Pounds Per Square Inch	psi	—
kPa	Kilopascals	kPa	—

💡

Pro Tip

Tyre pressure gauges read gauge pressure (above atmospheric). Absolute pressure = gauge pressure + 1 atm.
