Millimeter of Mercury to Pascal
1 mmHg = 133.322 Pa
How to convert millimeter of mercury to pascal
Enter the value in millimeter of mercury (mmHg) above and the equivalent in pascal (Pa) updates as you type. This conversion comes up when inflating tires with a gauge in a different unit than the door-sticker spec.
Typical situations: reading weather maps (hPa/mbar) vs US forecasts (inHg); diving and scuba tank pressures (bar vs psi).
You can also convert in the other direction: Pascal to Millimeter of Mercury
Millimeter of Mercury to Pascal conversion table
| Millimeter of Mercury (mmHg) | Pascal (Pa) |
|---|---|
| 1 | 133.322 |
| 2 | 266.644 |
| 5 | 666.61 |
| 10 | 1,333.22 |

Watch out for
- kPa, hPa, and bar are all metric but differ by factors of 100/1000; car specs are usually bar or kPa
- Absolute vs gauge pressure (psia vs psig): tire gauges read gauge pressure
