Factor1 hPa = 0.1 kPa
Converter
hPa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kPa
Rendered to 6 significant figures.
Formula
Formula
kPa = hPa × 0.1
Multiply any value in hectopascals by 0.1 to obtain the value in kilopascals.
Worked example
Convert 1000 hPa to kPa.
- 01Start with 1000 hPa.
- 02Multiply by the conversion factor: 1000 × 0.1 = 100 kPa.
Result1000 hPa = 100 kPa

FAQ
What is the conversion factor from hPa to kPa?
1 hPa equals 0.1 kPa. To convert, multiply the value in hectopascals by 0.1.
How do I convert 1 hPa to kPa?
1 hPa = 0.1 kPa. For any value, multiply by 0.1.
How do I convert kPa back to hPa?
Divide by the same factor — or equivalently, multiply by 10. So 1 kPa = 10 hPa.
When would I need to convert hectopascal to kilopascal?
Pressure conversions between hPa and kPa 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).
