Formula

Formula
cmH₂O = kgf/mm² × 100000

Multiply any value in kilograms-force per square millimetre by 100000 to obtain the value in centimetres of water column.

Worked example

Convert 1 kgf/mm² to cmH₂O.

  1. 01Start with 1 kgf/mm².
  2. 02Multiply by the conversion factor: 1 × 100000 = 100000 cmH₂O.
Result1 kgf/mm² = 100000 cmH₂O

FAQ

What is the conversion factor from kgf/mm² to cmH₂O?
1 kgf/mm² equals 100000 cmH₂O. To convert, multiply the value in kilograms-force per square millimetre by 100000.
How do I convert 1 kgf/mm² to cmH₂O?
1 kgf/mm² = 100000 cmH₂O. For any value, multiply by 100000.
How do I convert cmH₂O back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 1e-5. So 1 cmH₂O = 1e-5 kgf/mm².
When would I need to convert kilogram-force per square millimetre to centimetre of water column?
Pressure conversions between kgf/mm² 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).
