Convert attopascal to inch water (4°C)
Please provide values below to convert attopascal [aPa] to inch water (4°C) [inAq], or Convert inch water (4°C) to attopascal.
1 aPa = 4.0147e-21 inAq. To convert attopascal to inch water (4°C), multiply the value by 4.0147e-21; to go the other way, divide by it (1 inAq = 2.4908e+20 aPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aPa = 4.0147e-21 inAq
- 1 inAq = 2.4908e+20 aPa
- 10 aPa = 4.0147e-20 inAq
- 100 aPa = 4.0147e-19 inAq
How to Convert Attopascal to Inch Water (4°c)

Attopascal
The attopascal (aPa) is a unit of pressure equal to 10^-18 pascals, representing an extremely small pressure measurement.
History/Origin
The attopascal was introduced as part of the SI prefixes to denote very small quantities of pressure, but it is rarely used in practical applications due to its minuscule magnitude.
Current Use
The attopascal is primarily used in scientific research and theoretical contexts where extremely small pressure differences are relevant, although it remains largely a conceptual unit.
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.
