Enter the total length (in) and the total diameter (in) into the Calculator. The calculator will evaluate the Length-To-Diameter Ratio.

## Length-To-Diameter Ratio Formula

LDR = L / D

Variables:

- LDR is the Length-To-Diameter Ratio (in/in)
- L is the total length (in)
- D is the total diameter (in)

To calculate Length-To-Diameter Ratio, divide the overall length by the total diameter.

## How to Calculate Length-To-Diameter Ratio?

The following steps outline how to calculate the Length-To-Diameter Ratio.

- First, determine the total length (in).
- Next, determine the total diameter (in).
- Next, gather the formula from above = LDR = L / D.
- Finally, calculate the Length-To-Diameter Ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total length (in) = 1.25

total diameter (in) = 4.5
