Convert inch water (4°C) to kilopascal

Please provide values below to convert inch water (4°C) [inAq] to kilopascal [kPa], or Convert kilopascal to inch water (4°C).

1 inAq = 0.249082 kPa. To convert inch water (4°C) to kilopascal, multiply the value by 0.249082; to go the other way, divide by it (1 kPa = 4.01474213311 inAq). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Quick Reference

  • 1 inAq = 0.249082 kPa
  • 1 kPa = 4.01474213311 inAq
  • 10 inAq = 2.49082 kPa
  • 100 inAq = 24.9082 kPa

How to Convert Inch Water (4°c) to Kilopascal

Inch Water (4°c)

Inch water (4°C) is a unit of pressure measurement representing the pressure exerted by a one-inch column of water at 4 degrees Celsius.

History/Origin

The inch water (4°C) has been used historically in engineering and meteorology to measure low-pressure differences, especially in ventilation and HVAC systems, as a practical alternative to more complex units.

Current Use

Today, inch water (4°C) is primarily used in the United States for measuring low-pressure differences in HVAC, ventilation, and fluid systems, serving as a standard unit in these fields within the pressure converter category of common converters.


Kilopascal

The kilopascal (kPa) is a unit of pressure equal to 1,000 pascals, where one pascal is defined as one newton per square meter.

History/Origin

The kilopascal was introduced as part of the metric system to provide a convenient unit for measuring pressure, especially in scientific and engineering contexts, replacing larger units like the bar in many applications.

Current Use

The kilopascal is widely used today in various fields such as meteorology, engineering, and physics to measure pressure, including tire pressure, blood pressure, and atmospheric pressure.
