Converting from Inch of Water (inH₂0) to Kilopascal (kPa) | Pressure

What is Inch of Water (inH₂0)

An Inch of Water (inH₂0) is a unit of pressure widely used in the United States to measure low-pressure situations, such as air and gas pressures in HVAC systems. It represents the force of the weight of a 1-inch column of water at a specific temperature.

What is Kilopascal (kPa)

Kilopascal (kPa) is a unit of pressure in the metric system. It is commonly used in scientific and engineering applications to measure pressure levels, such as in weather forecasting, industrial processes, and fluid systems. One kilopascal is equivalent to one thousand pascals.

Conversion Formulas

The conversion formulas between Inch of Water (inH₂0) and Kilopascal (kPa) are as follows:

• To convert from Inch of Water to Kilopascal:
  kPa=inH2​0×0.2490889
• To convert from Kilopascal to Inch of Water:
  inH2​0=kPa×4.014631

Examples

1. Converting 13 inH₂0 to kPa:

   13inH2​0=13×0.2490889≈3.238156kPa

2. Converting 15 kPa to inH₂0:

   15kPa=15×4.014631≈60.21946inH2​0

3. Converting 14 inH₂0 to kPa:

   14inH2​0=14×0.2490889≈3.487245kPa
