What is the formula for percent error?

Hello, The difference between the Theoretical value and Experimental value, as a percentage of the Theoretical value, is known as a percentage error. Below is the formula:

Steps to solve:

1. Write down the above formula, keep it as a reference. The theoretical value is the exact value, and the Experimental value is the measured one.
2. Subtract the experimental value from the theoretical value. The difference will be considered as the magnitude of both the numbers.
3. Find the absolute value of the result.
4. Divide it by the Theoretical value and multiply it with 100. You will get the difference; as a result, place a percentage symbol beside it.
