Inches Of Mercury to Bar Converter
How to convert inches of mercury to bar
bar = inches of mercury ÷ 29.5299833
To convert inches of mercury to bar, divide the number of inches of mercury by 29.5299833.
1 inHg = 0.0338638864 bar
Examples
- Standard sea-level atmospheric pressure, as used for altimeter settings: 29.92 inHg ÷ 29.5299833 = 1.01320748 bar
- 30 inHg ÷ 29.5299833 = 1.01591659 bar
Good to know
This is the conventional inch of mercury, about 3386.389 Pa. Values defined at a specific mercury temperature differ slightly, for example 3376.85 Pa at 60 °F.

Unit definitions
- Inch of mercury (inHg)
- An inch of mercury is the pressure exerted by a 1 inch column of mercury, conventionally about 3386.389 pascals. It is used in the United States for barometric pressure in weather reports and aviation.
- Bar
- A bar is exactly 100,000 pascals, slightly less than average atmospheric pressure at sea level. It is widely used in Europe for tire pressures, weather and industrial equipment.
