Percent of number calculator will give you the answer, it's 3.5. Without "Absolute Value" We can also use the formula without "Absolute Value". The theoreticalvalue (using physics formulas)is 0.64 seconds. The post has been corrected. http://setiweb.org/percent-error/percent-of-error-equation.php
You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm3. Solve for percent error Solve for the actual value. Since the experimental value is smaller than the accepted value it should be a negative error. You measure the sides of the cube to find the volume and weigh it to find its mass.

Calculation Instructions/Directions: Enter Measured Value - This is the measured value or result. This formula is always expressed as %. A small error means the measured value is close to the actual value.
Example, total=1,100 and you need to find percent that equals to 100. Answer: it's 300 from the first math problem. simple math calculators, we offer Addition Math Calculator, Subtraction Math Calculator, Multiplication Math Calculator and Division Math Calculator . What Is A Good Percent Error Please try again.
Enter Actual Value - This is the theoretical, known, true, correct, accepted or exact value. Percent Error Definition Copper's accepted density is 8.96 g/cm3. Please try again. http://www.calculator.net/percent-error-calculator.html Outputs/Solution: Percent Error - Percent error is the absolute value of the difference of the measured value and the actual value divided by the actual value and multiplied by 100.
so divide by the exact value and make it a percentage: 65/325 = 0.2 = 20% Percentage Error is all about comparing a guess or estimate to an exact value.
