**Relative Error and Percent Error**

Relative error is the amount of error your measurement contains when compared to the total measurement.

To calculate relative error, subtract the measured value by the real value and then divide the absolute of that number by the real value to get the relative error. We can then multiply by 100% to get the percent error.
