Enter the real speed (mph) and the scale into the Scale Speed Calculator. The calculator will evaluate the Scale Speed.

## Scale Speed Formula

The following two example problems outline the steps and information needed to calculate the Scale Speed.

SS = RS / SQRT(S)

Variables:

- SS is the Scale Speed (mph)
- RS is the real speed (mph)
- S is the scale

To calculate a scale speed, divide the real speed by the square root of the scale.

## How to Calculate Scale Speed?

The following steps outline how to calculate the Scale Speed.

- First, determine the real speed (mph).
- Next, determine the scale.
- Next, gather the formula from above = SS = RS / SQRT(S).
- Finally, calculate the Scale Speed.
- 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.

real speed (mph) = 100

scale = 2.5

SS = RS / SQRT(S)** **= ?
