Convert attopascal to foot water (4°C)
Please provide values below to convert attopascal [aPa] to foot water (4°C) [ftAq], or Convert foot water (4°C) to attopascal.
1 aPa = 3.3456e-22 ftAq. To convert attopascal to foot water (4°C), multiply the value by 3.3456e-22; to go the other way, divide by it (1 ftAq = 2.9890e+21 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 = 3.3456e-22 ftAq
- 1 ftAq = 2.9890e+21 aPa
- 10 aPa = 3.3456e-21 ftAq

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.
Foot Water (4°c)
Foot water (4°C), symbol ftAq, is a unit of pressure representing the height of a water column at 4°C that exerts a specific pressure.
History/Origin
The foot water (4°C) has been used historically in engineering and scientific contexts to measure pressure, especially in water-related applications, as an alternative to other pressure units like inches of water or meters of water. Its usage dates back to traditional measurements in hydraulic and civil engineering.
Current Use
Today, foot water (4°C) is primarily used in specialized fields such as hydrology, water management, and engineering to measure low pressures, particularly in systems involving water flow and pressure head calculations.
