About pressure conversions

Convert absolute pressures for engineering, weather, and tire measurements. No gauge-pressure offset is assumed.

Each unit is defined relative to one common base unit, so the same factors work consistently in both directions. Select any unit above to see its conversion formula, a worked example, and a reference table.
