How the Pressure Converter works
Every unit is converted through the pascal (one newton per square meter). Reference values: 1 kPa = 1,000 Pa, 1 bar = 100,000 Pa, 1 standard atmosphere = 101,325 Pa, 1 psi ≈ 6,894.76 Pa, and 1 mmHg ≈ 1 torr ≈ 133.32 Pa.
Common uses include tire pressure (psi or bar), weather and altitude (hPa or atm), blood pressure (mmHg) and engineering specifications (MPa).
