What is a Precision to Tolerance Ratio?

The Precision to Tolerance Ratio (PTR) is a measure of how well a process or measurement system can produce results within specified tolerance limits. It is used to evaluate the capability of a system to maintain precision relative to the allowed tolerance.

Example Calculation

Let's assume the following values:

Using the formula:

\[ PTR = \frac{0.02}{0.1} = 0.2 \]

The Precision to Tolerance Ratio (PTR) is 0.2.
