Background

Pressure conversion is essential in engineering, automotive, diving, and medicine. PSI in US industrial, bar in European engineering, kPa in science, mmHg in medicine.

Common Units and Uses

PSI for tyre pressure/US industry. Bar for EU engineering/diving. kPa for science/automotive. atm = standard atmospheric pressure.

Tyre Pressure Units

30–35 psi = 200–240 kPa = 2.0–2.4 bar. All express the same range — converting correctly is a safety issue.

Applications

Automotive and Tyre Pressure

32 psi = 220 kPa = 2.2 bar. Incorrect pressure affects safety, economy, and tyre life.

Engineering and Hydraulics

3,000 psi hydraulic system = 207 bar. Converting is routine for international equipment.

Medical and Atmospheric

Blood pressure: 120/80 mmHg. Atmospheric: 101.325 kPa = 1 atm.

Industrial Applications

Our pressure converter tool is commonly used in industrial settings to ensure accurate measurements and conversions. For example, in a manufacturing plant, our tool can be used to convert pressure readings from one machine to another, or to compare pressures across different production lines.
