Kilopascals to inch of mercury Conversion
1 kilopascals (kPa) is equal to 0.295299833 inch of mercury (inHg).
1 kPa = 0.295299833 inHg
or
1 inHg = 3.38638864 kPa
Formula
To convert a pressure from kilopascals (kPa) to inch of mercury (inHg), divide the pressure in kilopascals by 3.38638864
p(inHg) = p(kPa) / 3.38638864
Examples:
Convert 5 kilopascals to inch of mercury:
p(inHg) = 5kPa / 3.38638864 = 1.476499165 inHg
