Enter the density or weight per unit of length and the length into the calculator to determine the weight. This calculator can also evaluate any of the variables given the others are known.

Feet To Kg Formula

The following formula can be used to calculate weight in kilograms based on length in feet, given a known density or weight per unit of length.

W = D * L

Variables:

  • W is the weight in kilograms (Kg)
  • D is the density or weight per unit of length (Kg/ft)
  • L is the length in feet (ft)

To calculate the weight in kilograms, multiply the length in feet by the density or weight per unit of length. This will give you the weight in kilograms. Please note that this formula is only applicable when the density or weight per unit of length is known.

What is Feet To Kg?

Feet to Kg is not a valid conversion as they measure two different things. Feet is a unit of length in the imperial and U.S. customary systems, while kilogram (Kg) is a unit of mass in the metric system. Therefore, it’s not possible to convert feet to kilograms directly without additional information such as density or weight per unit of length.

How to Calculate Feet To Kg?

The following steps outline how to calculate the Feet To Kg using the formula W = D * L.


  1. First, determine the density or weight per unit of length (D) in kilograms per foot (Kg/ft).
  2. Next, determine the length (L) in feet (ft).
  3. Next, gather the formula from above = W = D * L.
  4. Finally, calculate the weight (W) in kilograms (Kg).
  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.

density or weight per unit of length (D) = 0.5 Kg/ft

length (L) = 10 ft
