Enter all but one of the width, length, thickness, and density into the calculator to determine the coil weight; this calculator can also evaluate any of the variables given the others are known.

Coil Weight Formula

The following formula is used to calculate the coil weight:

CW = (W * L * T * D) / (2 * 10^6)

Variables:

  • CW is the coil weight
  • W is the width of the coil
  • L is the length of the coil
  • T is the thickness of the coil
  • D is the density of the material

To calculate the coil weight, multiply the width of the coil by the length of the coil, then multiply the result by the thickness of the coil. Multiply the product by the density of the material. Finally, divide the result by 2 multiplied by 10^6.

What is a Coil Weight?

Coil weight, also known as coil mass or coil size, refers to the weight of a rolled coil of material. This is typically used in the steel industry to measure the weight of steel or aluminum coils. The coil weight is determined by the width, thickness, and length of the material in the coil, as well as the density of the material. It is an important factor in the handling, shipping, and processing of the coil. The coil weight can also impact the cost of the material, as heavier coils may require more resources to transport and process. Therefore, understanding the coil weight is crucial for manufacturers, suppliers, and customers in the steel and aluminum industries.

How to Calculate Coil Weight?

The following steps outline how to calculate the Coil Weight:


  1. First, determine the weight of the empty coil (in pounds).
  2. Next, determine the weight of the material being wound onto the coil (in pounds).
  3. Next, add the weight of the empty coil to the weight of the material being wound onto the coil.
  4. Finally, calculate the total weight of the coil.
  5. After inserting the variables and calculating the result, check your answer with a scale or weight measurement device.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Weight of empty coil (in pounds) = 10

Weight of material being wound onto the coil (in pounds) = 25
