**About PTFE Rod Weight Calculator (Formula)**

The PTFE rod weight calculator is a tool that can be used to determine the weight of a PTFE (Polytetrafluoroethylene) rod based on its length, diameter, and density. PTFE is a synthetic polymer commonly known by the brand name Teflon, and is used in a variety of applications due to its non-stick and heat-resistant properties.

The formula for calculating the weight of a PTFE rod is:

**PTFE-W = (π/4) x D^2 x L x d**

where:

- PTFE-W is the weight of the rod in pounds
- D is the diameter of the rod in inches
- L is the length of the rod in inches
- d is the density of PTFE in pounds per cubic inch (typically 0.079478 lbs/in^3)

The formula uses the volume of the PTFE rod to calculate its weight. The volume is determined by multiplying the area of the cross section of the rod (π/4 x D^2) by its length (L). The density of PTFE is then used to convert the volume into weight.

Using this formula, you can easily calculate the weight of a PTFE rod given its diameter, length, and density. This can be useful in a variety of applications, such as determining the weight of a PTFE rod needed for a specific project or calculating the shipping cost of PTFE rods based on their weight.
