Pressure Converter
Convert pressure and stress between psi, bar, kPa, MPa, atm, inches and feet of water column, and mmHg.
Formula
value in Pa = value × factor(from); result = value in Pa ÷ factor(to)Rules of thumb
- Gauge vs absolute: absolute pressure = gauge pressure + ~101.3 kPa (14.7 psi) at sea level.
- 1 bar ≈ 14.5 psi ≈ 10.2 m of water column. Every 10 m (33 ft) of water depth adds about 1 bar.
