kgf/mm²tomH₂O

Convert kilograms-force per square millimetre (kgf/mm²) to metres of water column (mH₂O).

Factor1 kgf/mm² = 1000 mH₂O

Converter

kgf/mm²

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

Result
1000mH₂O

Rendered to 6 significant figures.

Formula

Formula
mH₂O = kgf/mm² × 1000

Multiply any value in kilograms-force per square millimetre by 1000 to obtain the value in metres of water column.

Worked example

Convert 1 kgf/mm² to mH₂O.

  1. 01Start with 1 kgf/mm².
  2. 02Multiply by the conversion factor: 1 × 1000 = 1000 mH₂O.
Result1 kgf/mm² = 1000 mH₂O

FAQ

What is the conversion factor from kgf/mm² to mH₂O?
1 kgf/mm² equals 1000 mH₂O. To convert, multiply the value in kilograms-force per square millimetre by 1000.
How do I convert 1 kgf/mm² to mH₂O?
1 kgf/mm² = 1000 mH₂O. For any value, multiply by 1000.
How do I convert mH₂O back to kgf/mm²?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mH₂O = 0.001 kgf/mm².
When would I need to convert kilogram-force per square millimetre to metre of water column?
Pressure conversions between kgf/mm² and mH₂O 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).
