1 Bar = 750.06376 mmHg
How to convert Bar to mmHg
To convert Bar to mmHg, multiply the value in Bar by 750.06376. For example, 5 bar = 3,750.319 mmHg.
Going from Bar to mmHg means applying a fixed conversion factor: one Bar (bar) is exactly 750.06376 mmHg (mmHg). Type any number into the converter above and the equivalent updates instantly, or use the reference table for quick lookups.
Pressure conversions are used in weather forecasting, engineering, diving, automotive maintenance, and industrial processes. Different fields favor different units, making conversion a regular necessity.
Understanding Bar and mmHg
The pascal is the SI unit, but it's small, so kilopascals and bars are more practical for everyday use. PSI (pounds per square inch) dominates in US engineering and tire pressures, while atmospheres provide an intuitive reference point — 1 atm is roughly the air pressure at sea level. Weather reports use hectopascals or millibars, which are numerically identical.
How accurate is this conversion?
Pressure conversions are based on fixed physical definitions. One standard atmosphere equals exactly 101,325 pascals, and 1 bar equals exactly 100,000 pascals, so all conversions here are precise.
All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
Quick reference: common Bar to mmHg values
The most frequently searched conversions are 1 Bar = 750.06376 mmHg, 5 Bar = 3,750.319 mmHg, 10 Bar = 7,500.638 mmHg, and 100 Bar = 75,006.376 mmHg. The full table further down covers every common value, and the calculator handles any number you need in between.
Pro tip: For tire pressure, most vehicles specify PSI in the US and bar or kPa elsewhere. As a rule of thumb, 1 bar ≈ 14.5 PSI, so a typical 2.2 bar tire pressure is about 32 PSI.
