Convert Standard atmosphere to centimeter water (4°C)
Please provide values below to convert Standard atmosphere [atm] to centimeter water (4°C) [cmH2O], or Convert centimeter water (4°C) to Standard atmosphere.
How to Convert Standard Atmosphere to Centimeter Water (4°c)
1 atm = 1033.25590075033 cmH2O
Example: convert 15 atm to cmH2O:
15 atm = 15 × 1033.25590075033 cmH2O = 15498.8385112549 cmH2O

Standard Atmosphere
The standard atmosphere (atm) is a unit of pressure defined as 101,325 pascals, representing the average atmospheric pressure at sea level.
History/Origin
The standard atmosphere was established in the early 20th century to provide a consistent reference for pressure measurements, based on the average atmospheric pressure at sea level under standard conditions.
Current Use
The atm is commonly used in fields such as meteorology, aviation, and engineering to express pressure, especially in contexts involving gases and atmospheric conditions.
Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
