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

Grams To Psi Formula

The following formula is used to calculate the pressure in PSI from mass in grams.

PSI = (g * 0.00220462) / A


  • PSI is the pressure in pounds per square inch is the mass in grams
  • A is the area in square inches over which the mass is distributed

To calculate the pressure in PSI, convert the mass from grams to pounds by multiplying it by 0.00220462 (since 1 gram is approximately 0.00220462 pounds). Then, divide the result by the area in square inches. This gives the pressure exerted by the mass over the given area in PSI.

What is Grams To Psi?

Grams to PSI is not a direct conversion as they measure two different things. Grams is a unit of mass in the metric system, while PSI (Pounds per Square Inch) is a unit of pressure in the Imperial system. To convert grams to PSI, additional information is needed such as the area over which the mass is distributed. If the context is about pressure, then it’s likely that the mass (in grams) is exerted over a certain area, and you would need to know this area to calculate the pressure in PSI.

How to Calculate Grams To Psi?

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

  1. First, determine the mass in grams (g).
  2. Next, determine the area in square inches (A) over which the mass is distributed.
  3. Next, gather the formula from above = PSI = (g * 0.00220462) / A.
  4. Finally, calculate the Grams To 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:

mass in grams (g) = 500

area in square inches (A) = 10
