What this calculator does

Converts a measurement given in millimetre of waters into pascals using the defined conversion factor.

What your result means

The same quantity expressed in Pa instead of mmH₂O. Nothing about the measurement itself changes.

Formula and working

Pa = mmH₂O × 9.80665

  1. 1

    Start with your value

    10 mmH₂O

  2. 2

    Convert to pascal

    10 × 9.80665 = 98.0665 Pa

  3. 3

    Result

    10 mmH₂O = 98.0665 Pa

Frequently asked questions

Symbols and assumptions

mmH₂O
Input unit — millimetre of water
Pa
Output unit — pascal
  • Both units measure pressure and stress, so the physical quantity is unchanged by the conversion.
  • The relationship is exactly linear: 1 mmH₂O = 9.80665 Pa.
  • Values are converted through the SI base unit for this quantity rather than pair by pair.

  • A unit conversion changes how a number is expressed, not how it was measured — the answer can never be more accurate than the value entered.
  • Displayed figures are rounded for readability; the full stored precision of the Pa value is used in every onward calculation.
