Centipascal to Inch Water (4°c) Conversion Table
| centipascal | inch water (4°C) |

Centipascal
The centipascal (cPa) is a unit of pressure equal to one hundredth of a pascal, where 1 pascal (Pa) is the SI unit of pressure defined as one newton per square meter.
History/Origin
The centipascal was introduced as a smaller unit of pressure for more precise measurements, particularly in scientific and engineering contexts, although it is not widely used in practice. It derives from the pascal, the SI base unit established in 1960.
Current Use
The centipascal is rarely used in modern applications; pressure measurements typically utilize pascals or larger units such as kilopascals. It may appear in specialized scientific literature or calibration contexts where fine pressure distinctions are necessary.
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.
