Percent Deviation Calculator

Formula

The formula to calculate the percent deviation is:

$\text{D} = \frac{(\text{Xm} - \text{Xt})}{\text{Xt}} \times 100$

Where:

$\text{D}$ is the percent deviation (%)
$\text{Xm}$ is the measured value
$\text{Xt}$ is the true value

What is Percent Deviation?

A percent deviation is defined as the percentage difference between a measured value and a true value. It indicates how much a measured value deviates from the true value in percentage terms.

Example Calculation

Example:

Measured Value: 105
True Value: 100

Calculation:

$\text{D} = \frac{(105 - 100)}{100} \times 100 = \frac{5}{100} \times 100 = 5\%$
