Unit	Converted Value

Pressure is the force applied per unit area and is a critical concept in various scientific, engineering, and everyday applications. Understanding the different units of pressure and how to convert between them is essential, especially when dealing with various tools, machinery, or scientific experiments. The Pressure Conversion Table below will help you quickly convert between commonly used pressure units.

Common Pressure Units

Pressure can be expressed in several different units, including:

1. Pascal (Pa): The SI (International System) unit of pressure, which is defined as one newton per square meter (N/m²).
2. Bar: A metric unit of pressure, used primarily in meteorology and engineering.
3. Atmosphere (atm): Used to represent atmospheric pressure at sea level.
4. Pound per square inch (psi): Commonly used in the United States, especially for tire pressures and engineering applications.
5. Torr (mmHg): Used to measure pressure in vacuum systems and barometers. It is approximately equal to the pressure exerted by a 1 mm column of mercury.
6. Millimeters of mercury (mmHg): Used in medical and scientific applications, particularly for blood pressure measurements.

Pressure Conversion Table

Here’s a quick reference for converting between different pressure units:

Unit	Pascal (Pa)	Bar	Atmosphere (atm)	Pound per square inch (psi)	Torr (mmHg)	Millimeters of Mercury (mmHg)
Pascal (Pa)	1	0.00001	9.8692 × 10⁻⁶	0.000145038	0.00750062	0.00750062
Bar	100,000	1	0.9869	14.5038	750	750
Atmosphere (atm)	101,325	1.01325	1	14.696	760	760
Pound per square inch (psi)	6,894.76	0.0689476	0.068046	1	51.7149	51.7149
Torr (mmHg)	133.322	0.00133322	0.001315	0.0193368	1	1
Millimeters of Mercury (mmHg)	133.322	0.00133322	0.001315	0.0193368	1	1

How to Use the Table

To convert between pressure units, simply multiply the value by the conversion factor listed in the table. For example:

• To convert 10 bar to Pascal:
  $10 \, \text{bar} \times 100,000 \, \text{Pa/bar} = 1,000,000 \, \text{Pa}$

• To convert 5 psi to Torr (mmHg):
  $5 \, \text{psi} \times 51.7149 \, \text{Torr/psi} = 258.5745 \, \text{Torr}$

Importance of Pressure Conversions

Pressure conversions are essential in fields such as meteorology, automotive, engineering, and medicine. Whether you're calibrating pressure gauges, converting atmospheric pressure for scientific experiments, or checking tire pressure, the ability to switch between different units is vital for accurate measurements and successful application.

In summary, this Pressure Conversion Table provides an easy-to-use reference for quickly converting between various units of pressure, making it easier to work with different measurement systems in a wide range of fields.
