Enter the length (ft), the width (ft), and the thickness (in) into the Steel Plate Mass Calculator. The calculator will evaluate and display the Steel Plate Mass. 

Steel Plate Mass Formula

The following formula is used to calculate the Steel Plate Mass. 

Msp  =SL * SW* T/12 * 490

  • Where Msp is the Steel Plate Mass (lbs)
  • SL is the length (ft) 
  • SW is the width (ft) 
  • T is the thickness (in) 

How to Calculate Steel Plate Mass?

The following example problems outline how to calculate Steel Plate Mass.

Example Problem #1

  1. First, determine the length (ft).
    • The length (ft) is calculated to be : 5.
  2. Next, determine the width (ft). 
    • The width (ft) is measured to be: 6.
  3. Next, determine the thickness (in). 
    • The thickness (in) is found to be: 3.
  4. Finally, calculate the Steel Plate Mass using the formula above: 

Msp  =SL * SW* T/12 * 490

The values given above are inserted into the equation below and the solution is calculated:

Msp  =5 *6* 3/12 * 490 = 3675 (lbs)


Example Problem #2

The variables needed for this problem are provided below:

length (ft) = 8

width (ft) = 6

thickness (in) = 2

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

Msp  =SL * SW* T/12 * 490 = (lbs)
