How to Use This Converter

  1. Pick the source unit in From.
  2. Pick the target unit in To (e.g. psi for a tyre).
  3. Type the value; the converted pressure and ratio appear instantly.
  4. Tap swap to flip the direction.

What Is a Pressure Converter?

Pressure is force per area, with a pleasingly fractured unit landscape. Engineers reach for pascals and kilopascals. Tire shops use psi in the US and bar in Europe (32 psi is roughly 2.2 bar). Meteorology reports hectopascals or millibars (they're numerically identical: 1013 hPa = 1013 mbar = standard atmosphere). Vacuum gear and medical instruments still use mmHg and torr (the two are nearly the same, off by one part in 10 million).

Car owners checking the spare tyre, divers planning a dive, HVAC technicians reading gauges and chemistry students working through gas-law problems all need to cross between these. Standard atmosphere is the canonical anchor: 1 atm = 101.325 kPa = 1.01325 bar = 14.696 psi = 760 mmHg.

Internally the tool normalises to pascals and converts out, with the factor displayed.

Frequently Asked Questions

What is psi?
Pounds per square inch. Common for tire pressure. 1 psi ≈ 0.069 bar.
What is standard atmospheric pressure?
1 atm = 101,325 Pa = 14.696 psi = 1.01325 bar. At sea level.
Bar to psi?
1 bar ≈ 14.504 psi. Bar is common in Europe for tire pressure.
