What does the Pressure Converter work out?

Convert bar, psi, kPa, atm and mmHg. It is one of the Unit Converters tools on Mondo Knows.

How is the Pressure Converter calculated?

Tyre pressures in psi, weather in hectopascals, plumbing in bar, blood pressure in millimetres of mercury. The same physical quantity in six different dialects, all converted at once. The maths is short enough to check by hand: Every unit is defined by how many base units it is worth, so the conversion is value x factor(from) / factor(to).
