Factor1 kPa = 10.19716 cmH₂O

Converter

kPa

Accepts numbers or expressions, e.g. 150 + 14.7

Result
10.1972cmH₂O

Rendered to 6 significant figures.

Formula

Formula
cmH₂O = kPa × 10.19716

Multiply any value in kilopascals by 10.19716 to obtain the value in centimetres of water column.

Worked example

Convert 1 kPa to cmH₂O.

  1. 01Start with 1 kPa.
  2. 02Multiply by the conversion factor: 1 × 10.19716 = 10.1972 cmH₂O.
Result1 kPa = 10.1972 cmH₂O

FAQ

What is the conversion factor from kPa to cmH₂O?
1 kPa equals 10.19716 cmH₂O. To convert, multiply the value in kilopascals by 10.19716.
How do I convert 1 kPa to cmH₂O?
1 kPa = 10.1972 cmH₂O. For any value, multiply by 10.19716.
How do I convert cmH₂O back to kPa?
Divide by the same factor — or equivalently, multiply by 0.0980665. So 1 cmH₂O = 0.0980665 kPa.
When would I need to convert kilopascal to centimetre of water column?
Pressure conversions between kPa and cmH₂O 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).
