Frequently asked questions
What is the source unit in this conversion?
The source unit is the meter of water (mH2O). Meter of water column.
What is the destination unit in this conversion?
The destination unit is the hectopascal (hPa). Hectopascal is 100 pascal units.
How do I convert meter of water to hectopascal?
Multiply the meter of water value by 98.0665. For example, 10 mH2O × 98.0665 = 980.665 hPa.
Is the meter of water to hectopascal conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in meter of water needs to be compared with, or reported in, hectopascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert hectopascal back to meter of water?
Yes. Multiply the hectopascal value by 0.010197 to get meter of water.

About this conversion
This page converts meter of water (mH2O) to hectopascal (hPa) within the pressure converter.
Meter of water column. Hectopascal is 100 pascal units.
The formula is hectopascal = meter of water × 98.0665, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
