Review Your Chemistry Concepts Percent Error Definition See How To Calculate Absolute and Relative Error Quick Review of Experimental Error More from the Web Powered By ZergNet Sign Up for Our Percentage Error Formula You measure the sides of the cube to find the volume and weigh it to find its mass. If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. anchor 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
Percent error or percentage error expresses as a percentage the difference between an approximate or measured value and an exact or known value.
