The formula to calculate the Precision to Tolerance Ratio (PTR) is:
\[ PTR = \frac{P}{T} \]
Where:
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.
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.
