Convert Megapascals to Kilopascals

1 megapascal is 1,000 kPa. One megapascal is exactly 1000 kilopascals.

One megapascal is 1000 kilopascals. To convert megapascals to kilopascals, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A million pascals.

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 megapascals to kilopascals?

  1. 1.Take the measurement in megapascals.
  2. 2.Multiply by 1000 — that is how many kilopascals fit in one megapascal.
  3. 3.To go back the other way, divide by 1000, or multiply by 0.001.

Worked example: 25 megapascals to kilopascals

Formula
MPa × 1000 = kPa
Arithmetic
25 × 1000 = 25,000 kPa
Answer
25 MPa = 25,000 kPa

The factor is exact, so this figure is exact too — only the display is rounded.

What is a megapascal?

A million pascals. Concrete strength and hydraulic ratings are specified here: 30 MPa concrete is about 4,350 psi.

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.

How many kilopascals are in a megapascal?

One megapascal is 1000 kilopascals, exactly. Going the other way, one kilopascal is 0.001 megapascals. 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.

Questions people actually ask

How many kilopascals are in a megapascal?
1000. A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.
How do I convert kilopascals back to megapascals?
Divide by 1000, or multiply by 0.001 — they are the same operation.
