Common pressure conversion mistakes
-
One atmosphere is not exactly one bar: 1 atm = 1.01325 bar = 101.325 kPa. There is also the technical atmosphere (1 kgf/cm²) at about 0.981 bar. The ~1% differences rarely matter day to day, but engineering and diving calculations need the right unit.
-
Blood pressure uses mmHg (120/80) and weather reports use hPa (around 1,013), different units that must not be mixed: 760 mmHg = 1,013.25 hPa. One mmHg is about 1.33 hPa.
-
Hectopascals and millibars are exactly the same size: 1 hPa = 1 mbar. A chart showing 1,013 mbar and one showing 1,013 hPa agree perfectly, no conversion needed. Meteorology simply renamed the unit.
