Convert Between PSI, Bars, Pascals, and More
A pressure converter is a tool used to translate a measurement of pressure from one unit into another, such as pounds per square inch (PSI) to bar or pascals (Pa). It is essential for engineers, scientists, and anyone working with fluid dynamics or weather systems to easily switch between metric and imperial units.
What is a Pressure Converter?
A Pressure Converter is a tool used in physics and engineering to translate a measurement of pressure from one unit to another. Pressure, defined as force per unit area, is measured differently across various systems and applications. This calculator helps bridge the gap between the metric system's Pascals and the imperial system's PSI, which is crucial for engineers, scientists, meteorologists, and technicians working with fluid dynamics or materials science.
How It Works: Conversion Factors
The calculator operates by using a base unit (Pascals) and established conversion factors for all other units. When you input a value, it is first converted into Pascals and then reconverted into all other supported units for a comprehensive comparison.
- Select 'From' Unit: Choose the unit you are converting from (e.g., PSI).
- Enter Value: Input the numerical value of the pressure measurement.
- View Conversions: The calculator instantly displays the equivalent value in a full table of common pressure units.
Common Pressure Units Explained
| Unit | Description | Common Use |
|---|---|---|
| Pascal (Pa) | The SI unit of pressure, defined as one newton of force per square meter. It is a very small unit. | Scientific research, materials science. |
| Kilopascal (kPa) | 1,000 Pascals. A more practical unit for everyday pressures. | Meteorology, engineering. |
| Bar | Equal to 100,000 Pascals, it is very close to standard atmospheric pressure. | Meteorology, tire pressure (Europe), scuba diving. |
| Atmosphere (atm) | Represents the average atmospheric pressure at sea level on Earth, approximately 101,325 Pa. | Chemistry, physics, scuba diving. |
| Pounds per Square Inch (PSI) | An imperial unit of pressure based on avoirdupois units. | Tire pressure (US), industrial applications. |
| Torr | Defined as 1/760 of a standard atmosphere, approximately equal to the pressure exerted by a millimeter of mercury. | Vacuum measurements, high-pressure physics. |
Frequently Asked Questions
How do you convert PSI to bars?
To convert Pounds per Square Inch (PSI) to bars, you divide the PSI value by 14.5038. For example, 30 PSI is approximately 2.07 bar.
What is the standard atmospheric pressure?
Standard atmospheric pressure at sea level is defined as 1 atmosphere (atm), which is equal to 101,325 Pascals, 1.01325 bar, or approximately 14.7 PSI.
What is a Pascal (Pa)?
The Pascal (Pa) is the SI unit of pressure. It is defined as one newton per square meter. Because it is a very small unit, pressure is often measured in kilopascals (kPa).
