When you need to convert millimetre of mercury to bar
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 0.000666612 bar, and 100 mmHg works out to roughly 0.1333 bar. Because the ratio is fixed at 0.0013, you can scale any amount linearly — doubling the mmHg doubles the bar.
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 bar
One millimetre of mercury equals 0.0013 bar. To convert, multiply the number of mmHg by 0.0013:
bar = mmHg × 0.0013
For example, 10 mmHg × 0.0013 = 0.0133 bar.
