1 hPa (hectopascals) = 1.019716213 cmH₂O (cmh₂o)

How to Convert Hectopascals to cmH₂O

The hectopascal and centimeter of water are both units of pressure. 1 hectopascal equals 1.019716213 cmh₂o. This means to convert hectopascals to cmh₂o, you multiply by 1.019716213.

Formula

cmh₂o = hectopascals × 1.019716213

Step-by-Step Example

Convert 5 hPa to cmh₂o:

1
Convert 5 hPa to cmh₂o

We need to convert hectopascals to cmh₂o

2
Apply the formula

Since 1 hPa = 1.019716213 cmH₂O, multiply by 1.019716213

5 × 1.019716213 = 5.0985810649

Answer

5 hPa = 5.0985810649 cmH₂O

About These Units

Hectopascal (hPa)

A hectopascal (hPa) equals 100 Pascals and is identical to one millibar. Hectopascals are the standard unit for atmospheric pressure in meteorology and aviation worldwide. Standard sea level pressure is 1013.25 hPa. Weather maps display pressure in hPa.

Centimeter of Water (cmH₂O)

Centimeters of water (cmH₂O) measure low pressures in medical ventilators, CPAP machines (4-20 cmH₂O), HVAC systems, and manometers. One cmH₂O equals 98.07 Pascals. Based on the pressure exerted by a water column.
