Weight Formulas

Knowing the weight of your material can be important when planning any project. Listed below are formulas to some of the most common types of metal products. The density has already been provided below; however, you can find additional densities for other materials listed on our Density Factors resource page.

ROUNDS

Steel:
Lbs. per lineal foot = D² x 2.669
Lbs. per lineal inch = D² x .2224

Aluminum:
Lbs. per lineal foot = D² x .924
Lbs. per lineal inch = D² x .077

 

FLATS

Steel:
Lbs. per lineal foot = A x B x 3.40
Lbs. per lineal inch = A x B x .2833

Aluminum:
Lbs. per lineal foot = A x B x 1.20
Lbs. per lineal inch = A x B x .10

 

SQUARES

Steel:
Lbs. per lineal foot = T² x 3.40
Lbs. per lineal inch = T² x .2833

Aluminum:
Lbs. per lineal foot = T² x 1.18
Lbs. per lineal inch = T² x .098

 

CIRCLES

Steel:
Wt. of Circle in lbs. = D² x T x .2224

Aluminum:
Wt. of Circle in lbs. = D² x T x .077
