Pressure Converter

Pressure Converter

Local Processing

Convert between pressure units including pascal, kilopascal, megapascal, bar, psi, atmosphere, torr, and mmHg.

How It Works & Processing Standards

Convert between the units listed below using Pa as the base unit.

kPa1 kPa = 1000 Pa
MPa1 MPa = 1000000 Pa
bar1 bar = 100000 Pa
psi1 psi = 6894.757293 Pa
atm1 atm = 101325 Pa
Torr1 Torr = 133.322368 Pa
mmHg1 mmHg = 133.322387 Pa

Tire pressure (psi, bar), weather (hPa), blood pressure (mmHg) and industrial equipment (MPa) all use different units; this converts between them.

How to Use Pressure Converter

  1. 1
    Enter a valueDecimals and negative numbers (for temperature, say) are accepted.
  2. 2
    Choose unitsPick the unit you have and the unit you want. The swap button reverses the direction.
  3. 3
    Read, copy or shareResults show up to six decimal places. Copy them or create a share link with the same value.

Examples

32 psi tire pressure in bar
Input: 32 psi → bar
Result: 2.206322
One atmosphere in kPa
Input: 1 atm → kPa
Result: 101.325

Common Use Cases

  • Recommended tire pressure in psi and bar
  • Matching compressor or hydraulic equipment units
  • Understanding weather and blood pressure units

Frequently Asked Questions (FAQ)

What about hPa?

1 hPa = 100 Pa = 0.1 kPa. 1013 hPa is 101.3 kPa.

Are torr and mmHg the same?

Almost, but they are defined slightly differently, so there is a tiny difference.
