Pressure unit converter
Convert between kg/cm², bar, psi, kPa, MPa, Pa, mbar, mmH₂O, inH₂O, mmHg, inHg and atm. Handy when a BOQ is in one unit and the gauge dial in another.
Reference values
| Parameter | Value |
|---|---|
| 1 kg/cm² | 0.980665 bar; 14.2233 psi; 98.0665 kPa |
| 1 bar | 1.01972 kg/cm²; 14.5038 psi; 100 kPa |
| 1 psi | 0.070307 kg/cm²; 0.068948 bar; 6.894757 kPa |
| 1 MPa | 10.1972 kg/cm²; 10 bar; 145.038 psi |
| 1 mmH₂O | 9.80665 Pa |
| 1 mmHg | 133.322 Pa |
| 760 mmHg | 1 atm = 101.325 kPa = 1.03323 kg/cm² |
Gauges can be printed with a dual scale, for example kg/cm² and psi, so nobody has to convert on site.
Questions buyers ask
How many psi is 1 kg/cm²?
1 kg/cm² = 14.223 psi = 0.98067 bar = 98.07 kPa.
Is bar the same as kg/cm²?
Nearly. 1 bar = 1.0197 kg/cm², a 2% difference, which is why Indian gauges are often printed in kg/cm² and export gauges in bar or psi.
How many pascals in 1 mmH₂O?
1 mmH₂O = 9.807 Pa, so 25 mmH₂O is about 245 Pa, a common AHU filter alarm setting.
