About Pressure Unit Conversion
The pressure converter suits air, hydraulic, tire and engineering pressure calculations in metric, imperial and common atmospheric units. You can also use the Temperature Unit Converter to handle lab, engineering and weather unit conversions together.
Common Formulas
- 1 kPa = 1000 Pa
- 1 MPa = 1000 kPa
- 1 bar = 100000 Pa
- 1 atm = 101325 Pa
- 1 psi ≈ 6.894757 kPa
Use Cases
- Tire, hydraulic and air pressure conversions
- Engineering pressure conversions between bar, psi, kPa and MPa
Tips
- Tire pressure is commonly shown in kPa, bar or psi; follow the vehicle manufacturer recommendation.
FAQ
How many psi is 1 bar?
1 bar ≈ 14.5037738 psi = 100000 Pa.
Does the converter support mmHg?
Yes. It includes mmHg and inHg, useful for atmospheric, medical and lab pressure conversions.
What are the common pressure units used for?
Pa/kPa/MPa (pascal) for engineering and science; bar for weather and industry; psi for tire pressure (car tires are often 30–35 psi); mmHg for blood pressure and medical monitoring; atm for standard atmosphere. The tool converts among all of them.
