About Converting Meter of waters to Decapascals
Meter of water and Decapascal both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Meter of water column, and decapascal is 10 pascal units.
Formula
decapascals = meter of waters × 980.665
This factor comes from each unit's defined relationship to the category's base unit: 1 meter of water equals 9806.65 base units, and 1 decapascal equals 10 base units, so dividing one by the other gives the direct meter of water-to-decapascal factor of 980.665.
Simple example
1 mH2O × 980.665 = 980.665 daPa
1 meter of water = 980.665 decapascals.
Real-world example
100 mH2O × 980.665 = 98,066.5 daPa
100 meter of waters = 98,066.5 decapascals.

Frequently asked questions
How many decapascals are in 1 meter of water?
1 meter of water equals 980.665 decapascals, using the exact defined conversion factor rather than an estimate.
How do I convert meter of water to decapascal?
Multiply the meter of water value by 980.665. The converter above does this instantly to whatever precision you set.
How do I convert decapascal back to meter of water?
Use the reverse factor: 1 decapascal equals 0.0010197162 meter of waters. You can also use the swap control in the converter above to flip the direction instantly.
What is a meter of water?
Meter of water (mH2O) is a unit of engineering.
What is a decapascal?
Decapascal (daPa) is a unit of engineering.
Is the meter of water to decapascal conversion exact?
Yes. Both meter of water and decapascal are defined by fixed standards rather than physical artifacts, so the factor of 980.665 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
