The kilopascal
The kilopascal (kPa) equals exactly 1,000 pascals. It is the standard pressure unit in modern meteorology, engineering specs outside the US, and most non-US tire-pressure recommendations.
Kilopascals to Inches of mercury Converter
1 kPa = 0.2953 inHg (kilopascal → inch of mercury)
1 kPa = 0.2953 inHg
1 kilopascal equals 0.2953 inches of mercury. To convert kilopascals to inches of mercury, multiply the kilopascal value by 0.2953. For quick reference: 1 kPa = 0.2953 inHg, 5 kPa = 1.4765 inHg, 10 kPa = 2.953 inHg, 100 kPa = 29.53 inHg.
Formula
Inches of mercury = Kilopascals × 0.2953Quick

- Are these conversion factors exact?
- The factor is derived directly from the SI definitions of kilopascal and inch of mercury; the displayed value is rounded for readability, and the browser computes using IEEE 754 double-precision arithmetic.
About the kilopascal and the inch of mercury
The inch of mercury
The inch of mercury (inHg) equals 3,386.389 Pa under the NIST SP 811 conventional definition. It is the standard unit for barometric pressure on US weather reports and for altimeter settings in US aviation.
