Kilopascals to Inches Of Mercury formula
The factor from kilopascals to inches of mercury is 0.295299802.
inHg = kPa × 0.295299802
Why this factor: the kilopascal and the inch of mercury are both defined against the pascal, so dividing one definition by the other gives 0.295299802 directly. Both definitions are set out in full below.
To go the other way, divide by 0.295299802 — or use the Inches Of Mercury to Kilopascals converter, which is the same calculation reversed.
Worked example
Start with 100 kPa. Multiply by 0.295299802 to get 29.52998 inHg.
100 kPa × 0.295299802 = 29.52998 inHg
The converter above does this for any value you type, in either direction.
What is a kilopascal?
A kilopascal is 1,000 pascals, the practical metric pressure unit.
Definition: Exactly 1,000 pascals. Standard atmospheric pressure is 101.325 kPa.
Where it is used: Tyre pressures outside the US, weather reports in Canada, and structural engineering loads.
What is an inch of mercury?
An inch of mercury is the pressure of a one-inch mercury column, used for US barometric pressure.
Definition: About 3,386.389 pascals.
Where it is used: US weather barometric pressure, aircraft altimeter settings, and engine vacuum readings.
Kilopascals vs Inches Of Mercury
The kilopascal is a metric unit while the inch of mercury is a US customary unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
