Actual results divided by your expected results. Subtract that number from 1. Multiply that by 100.
For example:
Actual result : 9 grams
Expected result: 10 grams
9/10 = .9
1 - .9 = .1
.1 x 100 = 10
10% error.

When you calculate results that are aiming for known values, the percent error formula is useful tool for determining the precision of your calculations. The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value.
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.
The difference between low percent error and high percent error is one is low and the other is high
The error in its area is then 2 percent....
