Convert Megapascals to Pascals

1 megapascal is 1,000,000 Pa. One megapascal is exactly 1000000 pascals.

One megapascal is 1000000 pascals. To convert megapascals to pascals, multiply by 1000000; to go the other way, divide by 1000000 or multiply by 1.0000 × 10^-6. 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 pascals?

  1. 1.Take the measurement in megapascals.
  2. 2.Multiply by 1000000 — that is how many pascals fit in one megapascal.
  3. 3.To go back the other way, divide by 1000000, or multiply by 1.0000 × 10^-6.

Worked example: 25 megapascals to pascals

Formula
MPa × 1000000 = Pa
Arithmetic
25 × 1000000 = 25,000,000 Pa
Answer
25 MPa = 25,000,000 Pa

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 pascal?

The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.

How many pascals are in a megapascal?

One megapascal is 1000000 pascals, exactly. Going the other way, one pascal is 1.0000 × 10^-6 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 pascals are in a megapascal?
1000000. The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.
How do I convert pascals back to megapascals?
Divide by 1000000, or multiply by 1.0000 × 10^-6 — they are the same operation.
