percent error calculator:

Percent error is used to compare a measured or experimental value to a known or accepted value. The formula for percent error is:

| (measured value – accepted value) / accepted value | x 100%

The resulting value will be a percentage representing the percent error. The absolute value of the difference is taken to ensure that the percent error is always positive.

Here’s an example to show you how to use the calculator:

Suppose you measured the weight of an object to be 50 grams, but the actual weight is 55 grams. What is the percent error?

Step 1: Calculate the absolute difference between the measured and accepted values: |50 – 55| = 5

Step 2: Divide the absolute difference by the accepted value: 5/55 = 0.0909

Step 3: Multiply by 100% to get the percent error: 0.0909 x 100% = 9.09%

So the percent error is 9.09%.

Here’s the calculator:

Input the measured value: 50 Input the accepted value: 55

Result: 9.09%
