Bar (bar) to Inches of mercury (inHg) Conversion
Bar
The bar is a unit of pressure equal to exactly 100,000 pascals (100 kPa), accepted for use with the SI by the BIPM. It is close to one standard atmosphere (1 atm = 1.01325 bar) making it convenient for many practical applications. The bar is widely used in meteorology (weather maps), industrial gas and fluid systems, and tyre inflation in continental Europe. A typical car tyre is inflated to 2.2–2.5 bar; scuba diving tanks are filled to 200–300 bar.
Inches of mercury
The inch of mercury (inHg) is a unit of pressure equal to the pressure exerted by a column of mercury 1 inch (25.4 mm) high — approximately 3,386.39 Pa or 0.0334 atm. It is used in US aviation for altimeter settings (standard pressure is 29.92 inHg) and in US weather reports for barometric pressure. Pilots set their altimeters in inHg based on local barometric pressure to ensure accurate altitude readings.
