Percent Error Calculator

What is Percent Error?

Percent error is a measure of how inaccurate a measurement is, expressed as the relative difference between the experimental value and the theoretical value. It's commonly used in scientific experiments and measurements to quantify the precision of results.

The Formula

Percent Error = |((Experimental - Theoretical) / Theoretical)| × 100%

How to Calculate Percent Error

  1. Obtain the experimental value from your measurement or experiment
  2. Identify the theoretical or accepted value
  3. Input both values into the calculator
  4. The calculator will automatically compute the absolute percent error
