Convert Kilopascals to Inches of mercury
1 kilopascal is 0.2953 inHg. One kilopascal is exactly 0.295299801647 inches of mercury.
One kilopascal is 0.2952998 inches of mercury. To convert kilopascals to inches of mercury, multiply by 0.2952998; to go the other way, divide by 0.2952998 or multiply by 3.386389. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand pascals, and the unit metric tyre placards and weather stations use.

How do you convert kilopascals to inches of mercury?
- 1.Take the measurement in kilopascals.
- 2.Multiply by 0.2952998 — that is how many inches of mercury fit in one kilopascal.
- 3.To go back the other way, divide by 0.2952998, or multiply by 3.386389.
Worked example: 25 kilopascals to inches of mercury
- Formula
- kPa × 0.2952998 = inHg
- Arithmetic

What is a kilopascal?
A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.
What is an inch of mercury?
The pressure of a one-inch column of mercury at 0 °C, fixed by convention at 3,386.389 pascals. US aviation altimeters and barometers read in it.
How many inches of mercury are in a kilopascal?
One kilopascal is 0.2952998 inches of mercury. Going the other way, one inch of mercury is 3.386389 kilopascals. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
