Why Convert Millimeters of Mercury to Torr?

Converting between millimeters of mercury (mmHg) and torr (Torr) is one of the most common pressure conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert mmHg to Torr saves time and prevents errors.

Pressure conversions between mmHg and Torr are vital in automotive maintenance, meteorology, and scuba diving. Tire pressure affects fuel efficiency and safety, requiring drivers to convert between PSI and bar depending on the gauge used. Divers must strictly monitor pressure to avoid decompression sickness, often needing to convert depth and tank pressure readings. In weather forecasting, atmospheric pressure changes indicate approaching storms, with data often shared in different units globally. Failing to convert pressure accurately can lead to equipment failure, tire blowouts, or life-threatening situations underwater.

How to Convert Millimeters of Mercury to Torr

To convert millimeters of mercury to torr, use the following formula:

Torr = mmHg × 1.000000142

Example: 1 mmHg = 1.000000142 Torr

For example, 5 mmHg = 5.000000712 Torr, 10 mmHg = 10.00000142 Torr, and 100 mmHg = 100.0000142 Torr. For larger values, 1000 mmHg = 1000.000142 Torr. Conversely, 1 Torr = 0.9999998575 mmHg. Our calculator above performs this conversion instantly with full precision — no rounding errors.

Common Mistakes to Avoid

Gauge vs Absolute: confusing gauge pressure (psig) with absolute pressure (psia).
Bar vs Pascal: 1 Bar is 100,000 Pascals, not 10 or 100.
Atmosphere variations: confusing standard atm with technical atm.

Pro Tips

Tire checks: Check tire pressure when cold (tires heat up and pressure rises while driving).
PSI rule: Typical car tires are 30-35 PSI.
Altitude effect: Air pressure drops as you go higher (ears popping).
