Enter the total velocity (mph) and the total weight (lbs) into the Calculator. The calculator will evaluate the Speed To Weight Ratio. 

Speed To Weight Ratio Formula

SWR = V / W


  • SWR is the Speed To Weight Ratio (mph/lb)
  • V is the total velocity (mph)
  • W is the total weight (lbs)

To calculate Speed To Weight Ratio, divide the total speed by the weight.

How to Calculate Speed To Weight Ratio?

The following steps outline how to calculate the Speed To Weight Ratio.

  1. First, determine the total velocity (mph). 
  2. Next, determine the total weight (lbs). 
  3. Next, gather the formula from above = SWR = V / W.
  4. Finally, calculate the Speed To Weight Ratio.
  5. 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 velocity (mph) = 839

total weight (lbs) = 12
