About Converting Meter of waters to Kilopascals
Meter of water and Kilopascal 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 kilopascal is 1000 pascal units.
Formula
kilopascals = meter of waters × 9.80665
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 kilopascal equals 1000 base units, so dividing one by the other gives the direct meter of water-to-kilopascal factor of 9.80665.
Simple example
1 mH2O × 9.80665 = 9.80665 kPa
1 meter of water = 9.80665 kilopascals.
Real-world example
100 mH2O × 9.80665 = 980.665 kPa
100 meter of waters = 980.665 kilopascals.

Frequently asked questions
How many kilopascals are in 1 meter of water?
1 meter of water equals 9.80665 kilopascals, using the exact defined conversion factor rather than an estimate.
How do I convert meter of water to kilopascal?
Multiply the meter of water value by 9.80665. The converter above does this instantly to whatever precision you set.
How do I convert kilopascal back to meter of water?
Use the reverse factor: 1 kilopascal equals 0.1019716213 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 kilopascal?
Kilopascal (kPa) is a unit of engineering.
Is the meter of water to kilopascal conversion exact?
Yes. Both meter of water and kilopascal are defined by fixed standards rather than physical artifacts, so the factor of 9.80665 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.
