How to convert inch of mercury to hectopascal
One inch of mercury equals 33.8638864 hPa, so multiply the number of inch of mercurys by 33.8638864:
hPa = inHg × 33.8638864
Going the other way
One hectopascal equals 0.0295299833 inHg, so to convert back:
inHg = hPa × 0.0295299833
Both directions are shown in the results above, and the drop-downs let you convert between any pair of pressure units — not just these two.
