About These Units
Inch of Mercury (inHg)
Inches of mercury (inHg) measure atmospheric pressure in US aviation and weather reports. Standard sea level pressure is 29.92 inHg. Altimeter settings use inHg. One inHg equals 25.4 mmHg or approximately 33.86 millibars.
Kilopascal (kPa)
A kilopascal (kPa) equals 1,000 Pascals or approximately 0.145 PSI. Kilopascals measure tire pressure in metric countries (typically 200-250 kPa for cars), blood pressure, and industrial processes. Standard atmospheric pressure is 101.325 kPa.
