Enter the rear-end ratio and the transmission first gear ratio into the Starting-Line Ratio Calculator. The calculator will evaluate and display the Starting-Line Ratio.
Starting-Line Ratio Formula
The following formula is used to calculate the Starting-Line Ratio.
STLR = RER *TFG
- Where STLR is the Starting-Line Ratio
- RER is the rear-end ratio
- TFG is the transmission first gear ratio
To calculate a starting-line ratio, multiply the rear-end ratio by the transmission first gear ratio.
How to Calculate Starting-Line Ratio?
The following example problems outline how to calculate Starting-Line Ratio.
Example Problem #1:
- First, determine the rear-end ratio.
- The rear-end ratio is given as: 2.5.
- Next, determine the transmission first gear ratio.
- The transmission first gear ratio is provided as: 5.3.
- Finally, calculate the Starting-Line Ratio using the equation above:
STLR = RER *TFG
The values given above are inserted into the equation below and the solution is calculated:
STLR = 2.5 *5.3 = 13.25
Example Problem #2:
For this problem, the variables required are provided below:
rear-end ratio = 1.5
transmission first gear ratio = 6
Test your knowledge using the equation and check your answer with the calculator above.
STLR = RER *TFG = ?
