This psi to cmH₂O conversion reference table provides accurate conversion factors for both SI and imperial units. All values are based on internationally recognized standards for maximum precision in scientific and engineering applications. One psi is defined as the pressure exerted by one pound-force applied over an area of one square inch.
What is PSI?
Pounds per square inch (psi) is a unit of pressure commonly used in the United States and other countries that use the imperial system. It represents the pressure resulting from a force of one pound-force applied to an area of one square inch. PSI is widely used in various applications, including tire pressure, industrial processes, and hydraulic systems. Our psi conversion tool helps you easily convert between psi and other pressure units. For example, 1 psi equals approximately 6,894.76 pascals or 0.0689476 bar.
Frequently Asked Questions
How many psi are in a cmH₂O?
There are approximately 0.0142233 psi in one cmH₂O.
Why is psi used in various applications?
PSI is widely used due to its practical relevance in many everyday and industrial applications. It provides a convenient and intuitive measure of pressure for things like tire inflation, water pressure in pipes, and hydraulic systems. Its direct relationship to pound-force and square inch makes it easy to understand in imperial measurement contexts.
How accurate is the psi to cmH₂O conversion?
The conversion is highly accurate as it is based on established physical constants. One cmH₂O is defined as 98.0665 pascals, and 1 psi is defined as 6,894.76 pascals. Therefore, 1 psi = 6,894.76 / 98.0665 ≈ 70.307 cmH₂O. This precision is sufficient for all practical applications.
What are common uses for psi to cmH₂O conversion?
This conversion is useful in fields where both industrial pressure measurements and general atmospheric pressures are considered. For example, in engineering, understanding how system pressures (in psi) relate to ambient atmospheric pressure (in cmH₂O) can be crucial for design and safety. It also finds application in some scientific research where pressure levels are compared against standard atmospheric conditions.
