how do you calculate percent uncertainty. This is the just the relative uncertainty multiplied by 100. Percent error percentage error is the difference between an experimental and theoretical value divided by the theoretical value multiplied by 100 to give a percent.

With Microsoft Excel you can measure the uncertainty of the samples.
Calculate the relative uncertainty. If youre taking a power of a value with an uncertainty you multiply the relative uncertainty by the number in the power. The absolute error is then divided by the true value resulting in the relative error which is multiplied by 100 to obtain the percentage error. To do this divide the uncertainty in the measurement by ACCURACY PRECISION AND UNCERTAINTY 4 the value of the measurement itself and then multiply by 100.
