Enter the foam length (ft), the foam width (ft), and the foam thickness (ft) into the Polyurethane Foam Weight Calculator. The calculator will evaluate the Polyurethane Foam Weight.

## Polyurethane Foam Weight Formula

The following formula is used to calculate the Polyurethane Foam Weight.

PFW = FL * FW * FT * 1.2

Variables:

• PFW is the Polyurethane Foam Weight (lbs)
• FL is the foam length (ft)
• FW is the foam width (ft)
• FT is the foam thickness (ft)

## How to Calculate Polyurethane Foam Weight?

The following two example problems outline the steps and information needed to calculate the Polyurethane Foam Weight.

Example Problem #1

1. First, determine the foam length (ft).
• The foam length (ft) is calculated to be : 3.
2. Next, determine the foam width (ft).
• The foam width (ft) is measured to be: 4.
3. Next, determine the foam thickness (ft).
• The foam thickness (ft) is found to be: .5.
4. Finally, calculate the Polyurethane Foam Weight using the formula above:

PFW = FL * FW * FT * 1.2

The values provided above are inserted into the equation below and computed.

PFW = 3 * 4 * .5 * 1.2 = 7.2 (lbs)

Example Problem #2

The variables required for this problem are provided below:

foam length (ft) = 6

foam width (ft) = 7

foam thickness (ft) = 1
