About Converting Meter of waters to Pascals
Meter of water and Pascal both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Meter of water column, and the pascal is one newton per square meter.
Formula
pascals = meter of waters × 9806.65
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 pascal equals 1 base unit, so dividing one by the other gives the direct meter of water-to-pascal factor of 9806.65.
Simple example
1 mH2O × 9806.65 = 9,806.65 Pa
1 meter of water = 9,806.65 pascals.
Real-world example
35 mH2O × 9806.65 = 343,232.75 Pa
35 meter of waters = 343,232.75 pascals.

Understanding the Meter of water (mH2O)
Meter of water column.
Understanding the Pascal
Pascal (Pa) measures pressure. The pascal is the SI derived unit of pressure: one newton of force per square meter. It is classified as a SI derived unit.
Where it's used: Standard scientific pressure unit worldwide
Uses of the Pascal today
- Scientific and engineering pressure measurement worldwide
- Meteorology (often as hectopascals, equivalent to millibars)
- Material science (stress and strength, typically in megapascals)
History of the Pascal
The pascal is named after Blaise Pascal, whose 17th-century experiments clarified the physics of fluid pressure and vacuum. It was adopted as the SI derived unit of pressure in 1971, replacing the older, non-coherent CGS pressure units used in much scientific work up to that point.
Historical origin. Pascal was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many pascals are in 1 meter of water?
1 meter of water equals 9,806.65 pascals, using the exact defined conversion factor rather than an estimate.
How do I convert meter of water to pascal?
Multiply the meter of water value by 9806.65. The converter above does this instantly to whatever precision you set.
How do I convert pascal back to meter of water?
Use the reverse factor: 1 pascal equals 0.0001019716 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 pressure.
What is a pascal?
Pascal (Pa) measures pressure. The pascal is the SI derived unit of pressure: one newton of force per square meter. It is classified as a SI derived unit.
Is the meter of water to pascal conversion exact?
Yes. Both meter of water and pascal are defined by fixed standards rather than physical artifacts, so the factor of 9806.65 used above is exact to as many digits as you choose to display.
