What is a pressure converter?
A pressure converter is a tool that allows you to convert between different units of pressure measurement, such as Pascal (Pa), kilopascal (kPa), megapascal (MPa), bar, atmosphere (atm), PSI, Torr, and mmHg.
How do I convert PSI to bar?
1 PSI equals approximately 0.0689476 bar. To convert PSI to bar, multiply the PSI value by 0.0689476. For example, 100 PSI = 6.895 bar.
What is standard atmospheric pressure?
Standard atmospheric pressure (1 atm) is 101,325 Pa, 101.325 kPa, 1.01325 bar, or 14.696 PSI. This is the average pressure at sea level on Earth.
What is the difference between Torr and mmHg?
Torr and mmHg are nearly identical units. 1 Torr = 1 mmHg = 133.322 Pa. They are both based on the height of a mercury column in a barometer.
How do I convert bar to PSI?
1 bar equals approximately 14.5038 PSI. To convert bar to PSI, multiply the bar value by 14.5038. For example, 2 bar = 29.008 PSI.
What is the SI unit of pressure?
The SI unit of pressure is the Pascal (Pa), named after Blaise Pascal. 1 Pa = 1 Newton per square meter (N/m²).
How do I convert kPa to PSI?
1 kPa equals approximately 0.145038 PSI. To convert kPa to PSI, multiply the kPa value by 0.145038. For example, 200 kPa = 29.008 PSI.
What is absolute vs gauge pressure?
Absolute pressure is measured relative to a perfect vacuum (zero pressure). Gauge pressure is measured relative to atmospheric pressure. Absolute = Gauge + Atmospheric pressure.
How do I convert mmHg to atm?
1 mmHg equals approximately 0.00131579 atm. To convert mmHg to atm, divide the mmHg value by 760. For example, 760 mmHg = 1 atm.
What is the difference between MPa and kPa?
1 MPa (megapascal) equals 1,000 kPa (kilopascal). MPa is used for high-pressure applications like hydraulics, while kPa is common in weather and tire pressure.
How do I convert inHg to mmHg?
1 inHg (inch of mercury) equals approximately 25.4 mmHg. To convert inHg to mmHg, multiply the inHg value by 25.4.
