Convert millimeter of mercury to pascal
Millimeter of mercury
The millimeter of mercury (mmHg) is a manometric unit of pressure defined as the pressure exerted by a column of mercury exactly 1 millimeter high at 0 °C under standard gravity. One mmHg equals approximately 133.322 pascals. It remains in widespread clinical use for measuring blood pressure and intraocular pressure.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
