Convert pressure in an instant

Type a value in any field — Pa, kPa, bar, psi, atm, mmHg — and read all equivalents. Ideal for tire pressure, weather and physics.

  1. Pick a unit

    bar, psi, Pa…

  2. Type a value

    The others compute themselves.

  3. Read the references

    Equivalence table.

Key equivalents

  • 1 bar = 100,000 Pa
  • 1 bar ≈ 14.5 psi
  • 1 atm = 101,325 Pa
  • 1 psi ≈ 6,895 Pa

Frequently asked questions

How many psi in a bar?

1 bar = 100,000 Pa = 14.504 psi ≈ 0.987 atm. 1 atmosphere = 101,325 Pa = 14.696 psi. 1 psi ≈ 6,895 Pa.

How do the linked fields work?

All units share the pascal as a base. Type a value in one field and the others update instantly.

Bar or atmosphere?

Very close: 1 bar = exactly 100,000 Pa, while 1 atm = 101,325 Pa (standard atmospheric pressure). The gap is about 1.3%.
