The centimeter of water (cmH₂O) is a unit of pressure defined as the pressure exerted by a column of water exactly one centimeter high at a standard gravitational acceleration. This unit is commonly used in various scientific and engineering applications, particularly in fields related to fluid mechanics and hydraulics.
The centimeter of water is part of the metric system and is standardized based on the density of water at a specific temperature. It is often utilized in contexts where low-pressure measurements are required, such as in medical applications (e.g., measuring pressure in respiratory systems) and environmental studies.
The use of water columns to measure pressure dates back to the early experiments in fluid mechanics. The centimeter of water has evolved as a practical unit for measuring pressure in various scientific disciplines, allowing for easier calculations and comparisons. Over time, it has become a standard unit in many industries, reflecting the need for precise pressure measurements.
To convert pressure from centimeters of water to pascals (Pa), you can use the following formula: 1 cmH₂O = 98.0665 Pa
For example, if you have a pressure of 50 cmH₂O, the equivalent pressure in pascals would be: 50 cmH₂O × 98.0665 Pa/cmH₂O = 4903.325 Pa
The centimeter of water is particularly useful in applications such as:

The term mmHg, or millimeters of mercury, is a unit of pressure defined as the pressure exerted by a column of mercury exactly 1 millimeter high at the acceleration of gravity. It is commonly used in various scientific and medical applications, particularly in measuring blood pressure and atmospheric pressure.
The mmHg unit is standardized in the International System of Units (SI) and is equivalent to approximately 133.322 pascals (Pa). This standardization allows for consistent measurements across different scientific disciplines, ensuring accuracy and reliability in data reporting.
The use of mercury in pressure measurement dates back to the 17th century when Evangelista Torricelli invented the barometer. The mmHg unit gained prominence due to its practicality and the density of mercury, which provides a clear and measurable standard for pressure. Over the years, mmHg has been widely adopted in both clinical settings for blood pressure readings and in meteorology for atmospheric pressure measurements.
To convert a pressure reading from mmHg to pascals, you can use the following formula:
[ \text{Pressure (Pa)} = \text{Pressure (mmHg)} \times 133.322 ]
For instance, if you have a pressure reading of 760 mmHg, the equivalent in pascals would be:
[ 760 , \text{mmHg} \times 133.322 , \text{Pa/mmHg} = 101325.2 , \text{Pa} ]
The mmHg unit is primarily used in the medical field to measure blood pressure, where normal readings are typically around 120/80 mmHg. Additionally, it is used in meteorology to report atmospheric pressure, with standard atmospheric pressure defined as 760 mmHg at sea level.
To utilize the mmHg conversion tool effectively, follow these steps:
