What is the percent error between 680 and 690?
Use this calculator when comparing a experimental value to a theoretical value. We think you reached us looking for answers to questions like: 1) What is the percent error supposing 690 as the measured value and 680 as the calculated value? 2) What is the absolute error between 680 and 690 supposing 680 as the theoretical value? Or may be: What is the percent error between 680 and 690?

How to calculate Percent Error  Step by Step SolutionThe Percent Error Calculator uses this formula:
The terms "Experimental" and "Theoretical" used in the equation above are commonly replaced with similar terms. Some terms also used for experimental are "measured," "calculated," or "actual" and for theoretical the terms "accepted" and "calculated" are frequently used. Here are the solutions to the questions stated above:1) What is the percent error supposing 690 as the measured value and 680 as the calculated value?Use the above formula to find the percent error. So, replacing the given values, we havePercent error = [(690  680) / 680] x 100 = (10 / 680) x 100 = 1.4705882352941 % (positive error) In this case we have a % of positive error because the experimental is greater than the theoretical. 2) What is the absolute error between 680 and 690 considering 680 as the theoretical value?This problem is not about percent or relative error, but about absolute error. The solution is very simple:Absolute error, or error = Experimental  Theoretical = 690  680 = 10 (positive error)
