Convert inch water (4°C) to hectopascal
Please provide values below to convert inch water (4°C) [inAq] to hectopascal [hPa], or Convert hectopascal to inch water (4°C).
1 inAq = 2.49082 hPa. To convert inch water (4°C) to hectopascal, multiply the value by 2.49082; to go the other way, divide by it (1 hPa = 0.401474213311 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 = 2.49082 hPa
- 1 hPa = 0.401474213311 inAq
- 10 inAq = 24.9082 hPa
- 100 inAq = 249.082 hPa
How to Convert Inch Water (4°c) to Hectopascal
1 inAq = 2.49082 hPa

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.
Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
