Pressure Conversion Follow-Up Checks
Pressure searches often involve tire pressure, equipment specifications, weather values, and medical units. Convert the value, then keep the broader unit and safety context nearby.
- Compare psi, bar, kPa, MPa, atm, and mmHg in one place.
- Treat medical and safety-related conversions as reference values, not final advice.
- Move to the general converter when the same task also needs area, weight, or data units.

Pressure Unit Converter Guide
The pressure unit converter changes psi, bar, kPa, MPa, Pa, atm, mmHg, Torr, hPa, and kgf/cm² values. Start with the table for common answers: 1 MPa = 10 bar = 1000 kPa = 145.038 psi, 1 bar = 14.5038 psi, 1 psi = 6.89476 kPa, 2.5 bar = 36.26 psi, and 1 atm = 101.325 kPa = 760 mmHg.
How to Convert Pressure Units
- 1.Check the quick table first for common values such as 1 MPa, 0.1 MPa, 1 bar, 1 psi, 2.5 bar, 32 psi, and 1 atm.
- 2.Enter your pressure value when the table does not already show the answer.
- 3.Choose the source unit and target unit, then compare nearby common units such as psi, bar, kPa, MPa, atm, mmHg, hPa, and kgf/cm².
- 4.If the source says psia, psig, or kPa(abs), keep that pressure reference separate from the unit conversion.
Pressure Unit Converter FAQ
Can it convert bar to psi?
Yes. bar, psi, Pa, kPa, MPa, atm, mmHg, and Torr conversions are supported. 1 bar is about 14.5038 psi.
How many psi is 2.5 bar?
2.5 bar is about 36.26 psi. Multiply bar by 14.5038 to convert bar to psi.
How do I convert psi to kPa?
1 psi is about 6.89476 kPa, so 32 psi is about 220.63 kPa.
How many bar is 1 MPa?
1 MPa is exactly 10 bar and 1000 kPa. It is also about 145.038 psi.
What is 1 atm in kPa and mmHg?
1 atm is exactly 101.325 kPa and 760 mmHg. It is also 1013.25 hPa and 1.01325 bar.
Does it show a pressure conversion table?
Yes. The page shows a quick pressure conversion table before the input form, then the calculator can compare the result across common pressure units.
Can I use it for tire pressure?
Yes. It is useful for comparing car and bicycle tire pressure units such as 2.2 bar, 2.5 bar, 30 psi, 32 psi, and 35 psi.
What is the difference between psia and psig?
The unit conversion factor is the same, but the pressure reference is different. psia is absolute pressure and psig is gauge pressure, so keep the original reference when checking equipment limits.
How many decimals are shown?
Results are formatted to keep the value readable for the selected units.
