The conversion calculation from inches of mercury column to millimetres of mercury column over the vacuum and atmospheric pressure range is as follows:

- 1 mmHg = 133.322 pascals (Pa)
- 1 inHg = 3386.39 pascals (Pa)
- mmHg value x 133.322 Pa = inHg value x 3386.39 Pa
**mmHg value = inHg value x 25.4**

Alternatively a simpler and more obvious calculation can be used from the known conversion factor for a length measured in inches converted to millimetres:

- 1 inch = 25.4 mm
**mmHg value = inHg value x 25.4**
