Step 2: Divide the error by the exact value (we get a decimal number) Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign) As What Is A Good Percent Error Please enter a valid email address. Tips Some teachers like the percent error to be rounded to a certain point; most people will be satisfied with the percent error rounded to three significant digits. It is often used in science to report the difference between experimental values and expected values.The formula for calculating percent error is:Note: occasionally, it is useful to know if the error

## Percent Error Calculator

Once you find the absolute value of the difference between the approximate value and exact value, all you need to do is to divide it by the exact value and multiply http://www.wikihow.com/Calculate-Percentage-Error 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. Percent Error Formula Chemistry How to find percent error: To correctly put together the percent error equation, take the difference from accepted value which is also your result minus the accepted value, divide by accepted Percent Error Definition If you want to know how to calculate percentage error, all you need to know is the approximate and exact value and you'll be on your way.
