What is the pressure converter?

The pressure converter is a collection of calculators for changing one pressure unit into another. Convert pressure units for tires, weather, hydraulics, engineering, pumps, and industrial measurements.

Pressure conversions are useful for tires, weather reports, barometers, hydraulics, compressed air systems, pumps, and engineering specifications.

Available pressure units

This category includes the following units:

Common pressure use cases

Use this category when the same measurement appears in different unit systems, data sheets, calculators, reports, or regional conventions.

These short unit notes help readers choose the right starting unit before opening a specific conversion page.

Pascal (Pa)

A pascal is the SI pressure unit equal to one newton per square meter. It is used in physics, engineering, and scientific pressure measurements.

Browse pascals conversions

Kilopascal (kPa)

A kilopascal is a metric pressure unit equal to 1,000 pascals. It is commonly used for weather, tire pressure in some regions, and engineering data.

Browse kpa conversions

Bar (bar)

A bar is a pressure unit close to atmospheric pressure. It is often used for tires, compressed air, scuba equipment, pumps, and industrial systems.

Browse bar conversions

Pound per Square Inch (psi)

Pounds per square inch is a pressure unit commonly used in the United States for tires, hydraulics, compressed air, and gauges.

Browse psi conversions

Standard Atmosphere (atm)

A standard atmosphere is a pressure unit based on average atmospheric pressure at sea level. It is commonly used as a reference in science and engineering.

Browse atm conversions

Torr (Torr)

A torr is a pressure unit often used in vacuum measurement, laboratory work, and applications where pressure is compared with millimeters of mercury.
