When you need to convert millimetre of mercury to pascal

Pressure conversions are used for tyre inflation, weather readings, scuba and industrial gauges, and HVAC work, where gauges and manuals may be calibrated in different units.

Typical values: 0.5 mmHg is about 66.6612 Pa, and 5 mmHg works out to roughly 666.6119 Pa. Because the ratio is fixed at 133.3224, you can scale any amount linearly — doubling the mmHg doubles the pascals.

A single tyre or gauge spec is often printed in two or three pressure units side by side for international use.

How to convert millimetre of mercury to pascal

One millimetre of mercury equals 133.3224 pascals. To convert, multiply the number of mmHg by 133.3224:

pascals = mmHg × 133.3224

For example, 10 mmHg × 133.3224 = 1333.22 pascals.
