Convert Kilopascals to Megapascals
1 kilopascal is 0.001 MPa. One kilopascal is exactly 0.001 megapascals.
One kilopascal is 0.001 megapascals. To convert kilopascals to megapascals, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. 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.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert kilopascals to megapascals?
- 1.Take the measurement in kilopascals.
- 2.Multiply by 0.001 — that is how many megapascals fit in one kilopascal.
- 3.To go back the other way, divide by 0.001, or multiply by 1000.
Worked example: 25 kilopascals to megapascals
- Formula
- kPa × 0.001 = MPa
- Arithmetic
- 25 × 0.001 = 0.025 MPa
- Answer
- 25 kPa = 0.025 MPa
The factor is exact, so this figure is exact too — only the display is rounded.

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 a megapascal?
A million pascals. Concrete strength and hydraulic ratings are specified here: 30 MPa concrete is about 4,350 psi.
How many megapascals are in a kilopascal?
One kilopascal is 0.001 megapascals, exactly. Going the other way, one megapascal is 1000 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.
