Enter the measured value and actual value into the calculator below to determine the relative error (%) and the absolute error. Re: Change from absolute to relative path in Power query. Thus, the key difference between absolute error and relative error is, absolute error is the magnitude of the difference between the exact value and the approximation whereas relative error is calculated by dividing the absolute error  by the magnitude of the exact value. The absolute and relative errors are very important parameters of numerical solvers. Textbook for College Mathematics. For example, if you measure the length of a book in centimeters (cm), the absolute error also has the same units. Our approach is that we first find the value of Absolute Error, and any value having the least absolute will be best. Absolute . In mathematics, science, and engineering we calculate various numbers, such as the current in an electric circuit, or the viscosity of the transmission fluid in a car, or the price of Ford Motor Company stock a year from now, or sin(1.5). There are two types of cell references: relative (relative) and absolute (absolute). Example: Consider we want to measure the length of a pencil using a ruler with millimeter marks.
