hPa to MPa converter

1 hectopascal equals 0.0001 megapascals. Conversions use MPa = hPa × 0.0001

hPa → 0.0001 MPa

MPa = hPa × 0.0001

Questions

How many megapascals in 1 hectopascal?

Exactly 0.0001 MPa. The factor follows from the definitions of both units, not from a measurement, so it is exact.

How do I convert hPa to MPa?

Multiply the hectopascals figure by 0.0001 — or use the converter above, which updates as you type.

Is hPa to MPa the same as MPa to hPa?

No — they are inverses. One hPa is 0.0001 MPa, while one MPa is 10,000 hPa.

What is 1 hPa in MPa?

1 hPa = 0.0001 MPa (see the value page for the full arithmetic).
