Convert torr to centimeter water (4°C)
Please provide values below to convert torr [Torr] to centimeter water (4°C) [cmH2O], or Convert centimeter water (4°C) to torr.
1 Torr = 1.35954723354 cmH2O. To convert torr to centimeter water (4°C), multiply the value by 1.35954723354; to go the other way, divide by it (1 cmH2O = 0.735538990727 Torr). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Torr
The torr is a unit of pressure defined as 1 millimeter of mercury (mmHg) at standard gravity and temperature, approximately equal to 133.322 pascals.
History/Origin
The torr was introduced by Evangelista Torricelli in 1644, based on his experiments with mercury barometers, as a unit to measure atmospheric pressure. It was historically used in meteorology and physics before the adoption of the pascal.
Current Use
Today, the torr is primarily used in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
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.
