About both units

From

Bar

bar

The bar equals 100,000 pascals — slightly less than one atmosphere (1.01325 bar). It is a convenient unit for everyday pressures: tyre pressures, diving depth, weather fronts. Common in European engineering.

Real-world: Car tyre: 2.0–2.5 bar. SCUBA at 10 m depth: 2 bar absolute. Fire hose: 5–7 bar.

Inch of Mercury

inHg

The inch of mercury equals about 3386 Pa. Used in US barometers, US aviation altimeter settings and some engineering. Standard sea-level pressure: 29.92 inHg.

Real-world: Sea-level standard: 29.92 inHg. Mountain pass at 3000 m: ~21 inHg. US aviation QNH given in inHg.

Tips & common mistakes

Quick tips

  • 1 bar = 100 kPa = 0.987 atm = 14.5 psi.
  • Almost 1 atm — convenient approximation.
  • Tyre pressures: 2.0–2.5 bar typical car, 6–10 bar truck.

Avoid these

  • Assuming 1 bar = 1 atm exactly — 1.3% off.
  • Mixing bar with psi — need factor of 14.5.
  • Using bar for high-pressure work — switch to MPa.
