Good to know
Espresso machines are rated around 9 bar of brewing pressure (130.5 psi). Pressure washers and air compressors are often sold in bar in Europe and psi in the US.
For kilopascals, 1 bar = 100 kPa, so 2.2 bar = 220 kPa — the unit some tire placards use.
US manual, metric tools? Ft-lbs to Nm converts the torque specs the same way.
