About pressure units
Pressure is force spread over an area. The pascal (one newton per square metre) is the SI unit, but it is small, so kilopascals and bars are common. One atmosphere (101,325 Pa) is roughly average sea-level air pressure. Tyres and industry often use psi (pounds per square inch), and medicine uses millimetres of mercury (mmHg).
Weather reports quote pressure in hectopascals (hPa), which equal millibars — 1,013 hPa is standard sea-level pressure.
