Percent Deviation Calculator
To find the percent deviation, subtract the theoretical value from the measured value, divide by the theoretical value, and multiply by 100 to get the percentage.
The Percent Deviation Calculator is used to calculate the percentage difference between an observed or measured value and an expected or theoretical value.
Widely used in scientific and statistical analyses, this calculation quickly highlights how far off a measured result is from a standard or expected outcome, making it essential for data comparison, quality control, and error analysis.
