Problem: The North American record for highest recorded barometric pressure is 31.85 inHg, set in 1989 in Northway, Alaska.Convert this pressure to kPa (kilopascals).

FREE Expert Solution

We’re being asked to find the barometric pressure in kPa (or kilopascals). The given pressure is in 31.85 inHg (or inches of Hg)


We will perform the following steps to solve the problem:

Step 1: Convert in Hg to mm Hg

Step 2: Convert mm Hg to kPa


Recall that when doing unit conversions:

▪ Put units you need to cancel out on opposite places (if it’s in the numerator then put the conversion factor with the same unit in the denominator)


Step 1: Convert in Hg to mm Hg


We’re going to convert in Hg to mm Hg:

in Hg → cm Hg → m Hg → mm Hg        

Hg does not change so we can do the conversion as:

in → cm → m → mm
