Formula
kilopascals = millimetres of mercury × 0.133322387
The millimetre of mercury used here is the conventional 133.322387415 Pa, defined from mercury density and standard gravity. It is very slightly larger than the torr, which is defined as exactly 1/760 of an atmosphere — so 760 mmHg is 1.00000014 atm, not exactly 1.
