Pressure conversion factors

1 bar = 100,000 Pa, 1 atm = 101,325 Pa, and 1 psi = 6,894.76 Pa. All conversions stem from Pascal as the base unit.

How to use

  1. Enter a pressure value.
  2. Select the unit you started with.
  3. Review the equivalent pressures in the remaining units.

Example

Input: Pressure = 2 bar

Output: ≈ 29.01 psi, ≈ 200 kPa, ≈ 1.97 atm

Deep dive & study plan

Pressure Converter: Converts between bar, atm, psi, and pascal units. It's built around pressure, bar, psi, so you can go from a raw question to a checked answer without switching tools.

The math behind it: 1 bar = 100,000 Pa, 1 atm = 101,325 Pa, and 1 psi = 6,894.76 Pa. All conversions stem from Pascal as the base unit.

To use it well: (1) Enter a pressure value. (2) Select the unit you started with. (3) Review the equivalent pressures in the remaining units. Keep your units consistent as you go, and re-run a case you already know the answer to — it's the fastest way to catch a typo before it throws off a result you're relying on.

Worked example: entering Pressure = 2 bar returns ≈ 29.01 psi, ≈ 200 kPa, ≈ 1.97 atm. Try swapping in your own numbers next, especially a case you're unsure about, before you use this for something that matters.

Quick retention checklist

  • Speak the formula aloud (or annotate it) so the relationships stick.
  • Write each step in your own words and compare with the numbered list above.
  • Swap in new numbers for the Example to make sure the calculator (and your logic) handles edge cases.
  • Check at least one related calculator below — it's the fastest way to confirm your numbers still line up from a different angle.

FAQ & notes

Why is Pascal the base unit?

Pascal is the SI unit for pressure, making it the most convenient anchor for reliable conversions.

Can I display kilopascals?

Yes—the panel shows pascals and kilopascals simultaneously so you can pick whichever scale suits the job.

What formula does the Pressure Converter use?

1 bar = 100,000 Pa, 1 atm = 101,325 Pa, and 1 psi = 6,894.76 Pa. All conversions stem from Pascal as the base unit.

How do I use the Pressure Converter?

Enter a pressure value. Select the unit you started with. Review the equivalent pressures in the remaining units.
