Weight Per Foot Calculator

What is Weight Per Foot?

How much something weighs per foot is called its weight per foot or WPF. It’s shown as pounds per foot (lbs/ft). This type measurement helps one to understand how weight spreads along things like steel beams, cables or any other linear material.

Formula

The formula used to calculate the weight per foot is:

$$\text{WPF}=\frac{\text{W}}{\text{L}}$$

$\text{L}$	Total Length	feet (ft)

How to Use the Calculator

The calculator offers both a basic and an advanced mode to suit different needs. Here’s how to use each mode:

1. Basic Calculator

In the Basic Calculator, you can calculate the weight per foot by entering any two of the following values:

• Total Weight (lbs): The full weight of the material.
• Total Length (ft): The total length of the material.
• Weight Per Foot (lbs/ft): The weight of the material per foot, which you want to calculate.

Example Calculation

Suppose you have the following details:

• Total Weight: 150 lbs
• Total Length: 50 ft

1. Enter 150 in the Total Weight field.
2. Enter 50 in the Total Length field.
3. Leave the Weight Per Foot field empty.

Using the formula:

$$\text{WPF}=\frac{\text{W}}{\text{L}}$$

We calculate:

$$\text{WPF}=\frac{150}{50}=3\text{lbs/ft}$$

So, the weight per foot is 3 lbs/ft.

Consider another scenario where the details are:

• Total Length: 100 ft
• Weight Per Foot: 2 lbs/ft

1. Leave the Total Weight field empty.
2. Enter 100 in the Total Length field.
3. Enter 2 in the Weight Per Foot field.

Using the formula:

$$\text{W}=\text{WPF}\times \text{L}$$

We calculate:

$$\text{W}=2\times 100=200\text{lbs}$$

So, the total weight is 200 lbs.

2. Advanced Calculator

The Advanced Calculator allows you to calculate the combined weight per foot for two different materials. You need to input the following fields:

• Total Weight for Material 1 (lbs): The weight of the first material.
• Total Length for Material 1 (ft): The length of the first material.
• Total Weight for Material 2 (lbs): The weight of the second material.
• Total Length for Material 2 (ft): The length of the second material.
• Combined Weight Per Foot (lbs/ft): The total weight per foot for both materials combined, which you want to calculate.

1. Example Calculation

Suppose you have the following details:

• Total Weight for Material 1: 80 lbs
• Total Length for Material 1: 40 ft
• Total Weight for Material 2: 120 lbs
• Total Length for Material 2: 60 ft

1. Enter 80 in the Total Weight for Material 1 field.
2. Enter 40 in the Total Length for Material 1 field.
3. Enter 120 in the Total Weight for Material 2 field.
4. Enter 60 in the Total Length for Material 2 field.

The advanced calculator will add the weights and lengths and then calculate the combined weight per foot:

1. Combined Weight = 80 + 120 = 200 lbs
2. Combined Length = 40 + 60 = 100 ft

Using the formula:

$$\text{Combined WPF}=\frac{200}{100}=2\text{lbs}$$

So, the combined weight per foot is 2 lbs/ft.
