Enter the weight and length into the calculator to determine the weight to length ratio. This calculator helps to evaluate the ratio of weight per unit length for various materials or objects.

Weight to Length Ratio Formula

The following formula is used to calculate the weight to length ratio.

R = W / L

Variables:

  • R is the weight to length ratio (pounds per foot)
  • W is the weight (pounds)
  • L is the length (feet)

To calculate the weight to length ratio, divide the weight by the length.

What is a Weight to Length Ratio?

The weight to length ratio is a measure of the density or distribution of weight along the length of an object or material. It is commonly used in industries such as construction, textiles, and cable manufacturing to ensure that materials meet specific strength and weight requirements. This ratio is also useful for calculating the load that can be supported over a given length of material without exceeding its tensile strength.

How to Calculate Weight to Length Ratio?

The following steps outline how to calculate the Weight to Length Ratio.


  1. First, determine the weight (W) in pounds.
  2. Next, determine the length (L) in feet.
  3. Next, gather the formula from above = R = W / L.
  4. Finally, calculate the Weight to Length Ratio (R) in pounds per foot.
  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.

Weight (W) = 50 pounds

Length (L) = 10 feet
