Equations
Millimetres of mercury to kilopascals
Pressure (kPa) = Pressure (mmHg) × 0.133322The displayed result is rounded to two decimal places, matching the authoritative legacy implementation.
Millimetres of mercury to centimetres of water
Pressure (cmH₂O) = Pressure (mmHg) × 1.35951The displayed result is rounded to the nearest whole centimetre of water, matching the authoritative legacy implementation.
