The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value. A percentage very close to zero means you are very close to your targeted value, which is good. It is always necessary to understand the cause of the error, such as whether it is due to the imprecision of your equipment, your own estimations, or a mistake in your experiment.Example: The 17th century Danish astronomer, Ole Rømer, observed that the periods of the satellites of Jupiter would appear to fluctuate depending on the distance of Jupiter from Earth. The further away Jupiter was, the longer the satellites would take to appear from behind the planet. In 1676, he determined that this phenomenon was due to the fact that the speed of light was finite, and subsequently estimated its velocity to be approx

Kick Images, Getty Images By Anne Marie Helmenstine, Ph.D. Chemistry Expert percent error definition chemistry Share Pin Tweet Submit Stumble Post Share By Anne Marie Helmenstine, Ph.D. Updated September 14, 2016. Percent error or percentage error expresses as a percentage the difference between an approximate or measured value and an exact or http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/ known value. It is used in chemistry and other sciences to report the difference between a measured or experimental value and a true or exact value. Here is how to calculate percent error, with an example calculation.Percent Error FormulaFor many applications, percent error is expressed as a positive value. The absolute value of the error is divided by an accepted value and given as a percent.|accepted value - experimental value| \ accepted value http://chemistry.about.com/od/workedchemistryproblems/a/percenterror.htm x 100%Note for chemistry and other sciences, it is customary to keep a negative value. Whether error is positive or negative is important. For example, you would not expect to have positive percent error comparing actual to theoretical yield in a chemical reaction.[experimental value - theoretical value] / theoretical value x 100%Percent Error Calculation StepsSubtract one value from another. The order does not matter if you are dropping the sign, but you subtract the theoretical value from the experimental value if you are keeping negative signs. This value is your 'error'. continue reading below our video 4 Tips for Improving Test Performance Divide the error by the exact or ideal value (i.e., not your experimental or measured value). This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.Percent Error Example CalculationIn a lab, you are given a block of aluminum. You measure the dimensions of the block and its displacement in a container of a known volume of water. You calculate the density of the block of aluminum to be 2.68 g/cm3. You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. Calculate the percent error of your meas
