observed, estimated or experimental value. Enter Actual Value - This is the theoretical, known, true, can percent error be negative correct, accepted or exact value. Outputs/Solution: Percent Error - Percent error is the absolute value of the difference of the measured value and the negative percent error actual value divided by the actual value and multiplied by 100. A small error means the measured value is close to the actual value. A large error means there may be something wrong with the experiment or equipment. Note, this calculator uses the absolute value method for error calculation. The

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 http://astro.physics.uiowa.edu/ITU/glossary/percent-error-formula/ 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 approximately 220,000 km/s. The current accepted value of the speed of light is almost 299,800 km/s. What was the percent error of Rømer's estimate?Solution:experimental value = 220,000 km/s = 2.2 x 108 m/stheoretical value = 299,800 km/s 2.998 x 108 m/s So Rømer was quite a bit off by our standards today, but considering he came up with this estimate at a time when a majority of respected astronomers, like Cassini, still believed that the speed of light was infinite, his conclusion was an outstanding contribution to the field of astronomy. © 2
Definition The percentage error, also known as percent error, is a measure of how innaccurate percent error a measurement is, standardized to how large the measurement is. It is the relative error expressed in terms of per 100. The relative error percent error calculator is calculated as the absolute error divided by the magnitude of the exact value. The absolute error is the magnitude of the difference between the actual value and the estimated value. Calculating Percent Error The percentage error calculation formula is as following: Percent error = (Estimated value - Actual value) / Actual value × 100% (in absolute value) ©2016 Miniwebtool | Terms and Disclaimer | Privacy Policy | Contact Us
