Greatest Possible Error (GPE) Calculator

Calculate Greatest Possible Error

Formula

The formula to calculate the greatest possible error (GPE) is:

\[ GPE = U \cdot 0.5 \]

What is the Greatest Possible Error?

The greatest possible error is a measure of how much error could be seen in a measurement, based on the units being measured. In more exact terms, the greatest possible error is 1/2 of the units of measure being used. For example, if the units of measure are inches, the greatest possible error is (1/2) = 0.5 inches.

Example Calculation

Let's assume the following value:

Using the formula to calculate the greatest possible error:

\[ GPE = 2 \cdot 0.5 = 1 \text{ inch} \]

The Greatest Possible Error (GPE) is 1 inch.
