Convert hectopascal to megapascal
Please provide values below to convert hectopascal [hPa] to megapascal [MPa], or Convert megapascal to hectopascal.
1 hPa = 0.0001 MPa. To convert hectopascal to megapascal, multiply the value by 0.0001; to go the other way, divide by it (1 MPa = 10000 hPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hPa = 0.0001 MPa
- 1 MPa = 10000 hPa
- 10 hPa = 0.001 MPa
- 100 hPa = 0.01 MPa
How to Convert Hectopascal to Megapascal
1 hPa = 0.0001 MPa
Example: convert 15 hPa to MPa:
15 hPa = 15 × 0.0001 MPa = 0.0015 MPa

Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
Megapascal
The megapascal (MPa) is a unit of pressure equal to one million pascals, where one pascal (Pa) is the pressure exerted by a force of one newton per square meter.
History/Origin
The megapascal was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring high pressures, especially in engineering and scientific applications, replacing larger units like the bar in many contexts.
Current Use
The MPa is widely used today in engineering, material science, and industrial applications to specify pressures in fields such as hydraulics, pneumatics, and structural engineering.
Frequently Asked Questions
What is 1 hectopascal in megapascal?
1 hectopascal (hPa) = 0.0001 megapascal (MPa).
How do you convert hectopascal to megapascal?
Multiply the hectopascal value by 0.0001. For example, 25 hPa × 0.0001 = 0.0025 MPa.
What is 10 hectopascal in megapascal?
10 hPa = 0.001 MPa.
Which unit is larger, the hectopascal or the megapascal?
The megapascal is the larger unit: 1 hPa equals only 0.0001 MPa.
