Enter the energy in Joules and the area in square meters into the calculator to determine the pressure in PSI. This calculator can also evaluate any of the variables given the others are known.

Joules To Psi Formula

The following formula is used to calculate the conversion from Joules to PSI.

PSI = J / (A * 0.000145038)


  • PSI is the pressure in pounds per square inch
  • J is the energy in joules
  • A is the area in square meters0.000145038 is the conversion factor from Pascal (Pa) to PSI

To calculate the pressure in PSI, divide the energy in joules by the area in square meters. Then, divide the result by the conversion factor 0.000145038 to convert from Pascal (Pa) to PSI.

What is Joules To Psi?

Joules to PSI is a conversion from a unit of energy (Joules) to a unit of pressure (Pounds per Square Inch). This conversion is not straightforward as they measure different physical quantities. Joules is a unit in the International System of Units (SI) used to quantify energy, work, or heat, while PSI is a unit of pressure commonly used in many different systems, including Imperial units and United States customary units. Therefore, a direct conversion between the two would typically involve an additional parameter such as area or volume.

How to Calculate Joules To Psi?

The following steps outline how to calculate the Joules To Psi using the given formula:

  1. First, determine the energy in joules (J).
  2. Next, determine the area in square meters (A).
  3. Next, gather the formula from above = PSI = J / (A * 0.000145038).
  4. Finally, calculate the pressure in pounds per square inch (PSI).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge:

energy in joules (J) = 500

area in square meters (A) = 2

conversion factor from Pascal (Pa) to PSI = 0.000145038
