Formula
Formula
Pa = hPa × 100
Multiply any value in hectopascals by 100 to obtain the value in pascals.
Worked example
Convert 10 hPa to Pa.
- 01Start with 10 hPa.
- 02Multiply by the conversion factor: 10 × 100 = 1000 Pa.
Result10 hPa = 1000 Pa

FAQ
What is the conversion factor from hPa to Pa?
1 hPa equals 100 Pa. To convert, multiply the value in hectopascals by 100.
How do I convert 1 hPa to Pa?
1 hPa = 100 Pa. For any value, multiply by 100.
How do I convert Pa back to hPa?
Divide by the same factor — or equivalently, multiply by 0.01. So 1 Pa = 0.01 hPa.
When would I need to convert hectopascal to pascal?
Pressure conversions between hPa and Pa are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
