About Megapascal and inHg

The megapascal is one million pascals, equal to one newton per square millimeter. Concrete strength, steel stress, and hydraulic systems are rated in megapascals. The inch of mercury is about 3,386.39 pascals. US weather reports and aviation altimeter settings quote barometric pressure in inches of mercury. One Megapascal equals 295.299833 inHg (1 MPa = 295.299833 inHg). Megapascal is used in concrete and steel strength ratings and in hydraulic system pressures. inHg is used in US barometric weather reports.

Precision and Rounding:Several pressure factors are exact by definition (1 atm = 101,325 Pa; 1 bar = 100,000 Pa) while others, like psi and mmHg, are derived and carry long decimals. Tire and weather readings tolerate whole-number rounding; calibration, medicine, and process engineering need the full factor before rounding.

Use the pressure conversion guide to compare mmHg, mbar, inHg, kPa, Pa, and torr across medical, weather, aviation, vacuum, and engineering work.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
