Convert pascals to inches of water

Explanation

From this page you can convert pascals to inches of water (or Pa to inH₂O) simply, by using the application above.

In case you are wondering, to convert from pascals to inches of water you need to multiply by 0.004015. This factor is calculated using the respective definitions of the two units you can find below.

The pascal (Pa) is the derived SI unit of pressure.

Definition of the pascal

One pascal is the pressure exerted by a force of one newton on a surface of one square meter.

The pascal is homogeneous to kilogram per meter per second squared.

Pa = N m^-2 = kg m⁻¹ s⁻²

Some Facts

The pascal is quite a small unit. A common housefly laying flat on your hand would apply a pressure of approximately 8 pascals.

The International System of Units

The International System of Units or SI (from the French Système international (d'unité)), also called metric system in the U.S., is a coherent system of units that was published 1960. It is official in nearly every country.

The General Conference on Weights and Measures (Conférence générale des poids et mesures) is tasked with overseeing the SI.
