The formula
kPa = mmHg × 0.133322
Worked through with a real value: 10 millimeters of mercury = 1.33322 kilopascals.
Going the other way: mmHg = kPa × 7.50062, so 1 kilopascal = 7.50062 millimeters of mercury.
What each unit is
- millimeter of mercury mmHg
- The pressure exerted by a one-millimetre column of mercury, used in medical equipment and scientific instruments.
- kilopascal kPa
- A thousand pascals, and the unit weather services and atmospheric measurements use worldwide.
Where these come from
- 1 millimeter of mercury = 133.322387415 pascals
- 1 kilopascal = 1000 pascals
Every other number on this page is computed from those, and each category is pinned to conversions worked out by hand from the units' primary definitions before it ships.
