Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100

Percent error is used when you are comparing your result to a known or accepted value. It is the absolute value of the difference of the values divided by the accepted value, and written as a percentage. Percent error is equal to the difference divided by the known times 100 percent.

Percent error is typically used to describe the difference between an expected value and an observed value (measured in an experiment). To calculate percent error, you must know the expected (or theoretical) value, determined from reference manuals and formulas. Percent error = [(actual measured value)/(expected value) - 1] x 100% Let's say that you do a chemistry experiment, where you expect to use 30 mL of a hydrochloric acid solution to neutralize a prepared solution of sodium hydroxide. When you perform the experiment, you actually use 30.2 mL of hydrochloric acid solution. Percent error = [(30.2 mL) / (30 mL) - 1] x 100% = 0.667 % error

If you mean percent error of 3.14 versus pi, which is 3.14159..., the error is only 0.05%

By definition of percent error, you can't. But you can approximate zero instead, with the number of decimals appropriate to the accuracy of the measurement, e.g. 0.01, 1E-100, etc.

Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.

Error percentage = (error value - theoretical value)/(theoretical value) * 100%You figure out the rest.PS, it looks like a really small percentage.

When you calculate results that are aiming for known values, the percent error formula is useful tool for determining the precision of your calculations. The formula is given by: The experimental value is your calculated value, and the theoretical value is your known value.

Percent error = (actual value - theoretical value) / theoretical value * 100%

Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100

A high percent error indicates that a certain value is very far from the accepted value. Percent error is the comparison of an estimated value to an exact one.

(experimental value - accepted value)/accepted value x 100 This is an absolute value, so ignore any minus sign.

Relative error percentage is a decimal percentage between 1 and 0 such that if you multiply the actual answer by (1-errorrel) you get your approximate value. In other words relative error is an indicator of how far away your apporximation is from the real value in terms of percent of the real value.

The formula of percent error ispercent error= Your value/accepted value x 100------------The definition of error is: difference between the accepted true value and the measured value of a quantity or parameter. But this is the absolute error.The relative (percent error) is:(measured value - accepted true value) . 100/accepted true valueThis value is exprssed as a percentage - %.
