Convert Pascals to Megapascals
1 pascal is 0.000001 MPa. One pascal is exactly 0.000001 megapascals.
One pascal is 1.0000 × 10^-6 megapascals. To convert pascals to megapascals, multiply by 1.0000 × 10^-6; to go the other way, divide by 1.0000 × 10^-6 or multiply by 1000000. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The SI unit: one newton spread over one square metre.

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 pascals to megapascals?
- 1.Take the measurement in pascals.
- 2.Multiply by 1.0000 × 10^-6 — that is how many megapascals fit in one pascal.
- 3.To go back the other way, divide by 1.0000 × 10^-6, or multiply by 1000000.
Worked example: 25 pascals to megapascals
- Formula
- Pa × 1.0000 × 10^-6 = MPa
- Arithmetic
- 25 × 1.0000 × 10^-6 = 0.000025 MPa
- Answer
- 25 Pa = 0.000025 MPa
The factor is rounded for display; the figure above is computed from the full value.

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.
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 pascal?
One pascal is 1.0000 × 10^-6 megapascals. Going the other way, one megapascal is 1000000 pascals. 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 megapascals are in a pascal?
- 1.0000 × 10^-6. A million pascals. Concrete strength and hydraulic ratings are specified here: 30 MPa concrete is about 4,350 psi.
- How do I convert megapascals back to pascals?
- Divide by 1.0000 × 10^-6, or multiply by 1000000 — they are the same operation.
