Where you'll actually use this
Pressure measures force per unit area. The SI unit is the pascal (Pa), but everyday use spans bar, psi, atm, mmHg, and torr.
- Tire pressure
Most cars list psi in the US, kPa or bar in Europe. 32 psi ≈ 2.2 bar ≈ 220 kPa.
- Weather
Atmospheric pressure is reported in hPa (hectopascals) or millibars (1 hPa = 1 mbar). 'Inches of mercury' (inHg) is still used in US aviation.
- Diving & medical
Blood pressure is measured in mmHg; scuba tank pressure in bar or psi.
Common mistakes to avoid
- Gauge vs absolute
Tire pressure is gauge pressure (relative to atmospheric). Absolute pressure adds ~1 atm (14.7 psi) on top.
Did you know?
Standard atmospheric pressure (101,325 Pa) is the force of a column of air reaching the top of the atmosphere.
