Unit Explanations
Centimeter of WatercmH₂O
Source UnitA centimeter of water (cmH₂O) is a unit of pressure defined as the pressure exerted by a column of water exactly 1 centimeter high at a specific temperature and gravity. It is commonly used in fields such as fluid mechanics and engineering, particularly for measuring low-pressure environments. The pressure generated is a result of the weight of the water column pressing down due to gravitational forces. This unit is particularly useful in applications where small pressure variations are significant, such as in medical devices and fluid systems.
Current Use
Today, the centimeter of water is widely used in various industries, including medical, HVAC, and environmental engineering. It is particularly relevant in areas such as respiratory therapy, where pressure settings are critical for patient care, and in HVAC systems where pressure drop across filters is monitored.
Fun Fact
1 cmH₂O is approximately equal to 98.0665 pascals, making it useful for measuring low pressures.
PascalPa
Target UnitThe pascal (Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus, and ultimate tensile strength. It is defined as one newton per square meter. In other words, it is the pressure exerted by a force of one newton acting uniformly over an area of one square meter. The pascal is a crucial unit in engineering, physics, and meteorology, providing a standard measure for atmospheric pressure, material strength, and force distribution. It allows for consistent and comparable measurements across various scientific and industrial fields.
Current Use
The pascal is widely used in various fields to measure pressure and stress. In meteorology, it is used to express atmospheric pressure, often in the form of hectopascals (hPa). In engineering, it helps evaluate the strength of materials and structures. The unit is also crucial in fluid mechanics, where it is used to determine fluid pressure in pipes and vessels. The pascal's versatility makes it a fundamental unit in both scientific research and practical applications, especially where precise pressure measurements are critical.
Fun Fact
The pascal is named after Blaise Pascal, who made significant contributions to the understanding of fluid pressure.

Definition
A centimeter of water (cmH₂O) is a unit of pressure defined as the pressure exerted by a column of water exactly 1 centimeter high at a specific temperature and gravity. It is commonly used in fields such as fluid mechanics and engineering, particularly for measuring low-pressure environments. The pressure generated is a result of the weight of the water column pressing down due to gravitational forces. This unit is particularly useful in applications where small pressure variations are significant, such as in medical devices and fluid systems.
History & Origin
The centimeter of water as a unit of pressure emerged from the need to measure small pressures in fluid systems, particularly in the 19th century as engineering practices advanced. It was established to provide a practical measurement scale for pressure that could be easily understood and applied in various scientific fields.
Etymology: The term 'centimeter' comes from the French 'centimètre,' which is a combination of 'centi-' meaning one hundredth and 'metre' meaning measure. The 'water' part denotes the fluid used to create the pressure column.

History & Origin
The pascal was named in honor of Blaise Pascal, a French mathematician, physicist, and inventor known for his contributions to fluid mechanics and the study of pressure. The unit was officially adopted as the SI unit for pressure in 1971, although the concept of pressure itself dates back to early scientific studies of fluids and gases. The pascal provided a standardized way to measure pressure, replacing a variety of non-standard units previously in use across different regions and industries.
Etymology: The term 'pascal' is derived from the name of Blaise Pascal.
