Frequently asked questions

What is the source unit in this conversion?

The source unit is the attopascal (aPa). Attopascal is 1e-18 pascal units.

What is the destination unit in this conversion?

The destination unit is the meter of water (mH2O). Meter of water column.

How do I convert attopascal to meter of water?

Multiply the attopascal value by 1.019716e-22. For example, 10 aPa × 1.019716e-22 = 1.019716e-21 mH2O.

Is the attopascal to meter of water 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 attopascal needs to be compared with, or reported in, meter of water, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.

Can I convert meter of water back to attopascal?

Yes. Multiply the meter of water value by 9.806650e+21 to get attopascal.

About this conversion

This page converts attopascal (aPa) to meter of water (mH2O) within the pressure converter.

Attopascal is 1e-18 pascal units. Meter of water column.

The formula is meter of water = attopascal × 1.019716e-22, 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.

Use the calculator above for instant results, or the table below for common attopascal values already converted to meter of water.
