Enter the length, width, and thickness of the rubber along with the density into the calculator to determine the rubber sheet weight.

Rubber Sheet Weight Formula

The following formula is used to calculate the weight of a sheet of rubber. 

RSW = L/12*W/12*T/12*D
  • Where RSW is the rubber sheet weight (lbs)
  • L is the length of the sheet (in)
  • W is the width of the sheet (in)
  • T is the thickness of the sheet (in)
  • D is the density of the sheet (lbs/ft^3)
    • The density of common neoprene rubber is 76.79 lbs/ft^3

To calculate the rubber sheet weight, calculate the volume of the sheet, then multiply the result by the density of the rubber.

What is the weight of rubber sheet?

Neoprene rubber, the most common type of rubber, has a density of 76.79 pounds per cubic foot. The total weight of a sheet would be the volume of the sheet in cubic feet multiplied by this density.

How to calculate neoprene rubber sheet weight?

Example Problem:

The following example outlines how to calculate a neoprene rubber sheet weight.

First, determine the length, width, and thickness of the sheet.

In this example, these are measured to be:

L = 12 inches

W = 8 inches

T = .500 inches

Next, determine the density of the rubber. In this case, the rubber is standard neoprene rubber which has a density of 76.79 lbs/ft^3.

Finally, calculate the rubber sheet weight using the formula above:

RSW = L/12*W/12*T/12*D

RSW = 12/12*8/12*.5/12*76.79

RSW = 2.133 lbs
