How accurate is this pipe weight calculator?

It uses standard densities for materials. However, actual weight may vary slightly due to manufacturing tolerances and alloy specifics.

Does the result include the weight of fluid inside?

No, this calculator only determines the weight of the empty pipe itself (the material).

Currently, Imperial length is measured in feet. For short lengths in inches, divide by 12 to get decimal feet.

This calculator is designed for engineers and contractors globally, supporting both primary unit systems. Use the toggle above to switch between:

Metric Units: Diameter and thickness in millimeters (mm), length in meters (m).
Imperial Units: Diameter and thickness in inches (in), length in feet (ft).

When switching units, the calculator automatically converts your current inputs so you don't lose your work.

To determine the weight of a pipe, the calculator performs these geometric steps:

Outer Volume: Calculates the volume of the full cylinder based on the Outer Diameter.
Inner Volume: Calculates the volume of the hollow center based on the wall thickness.
Material Volume: Subtracts the inner volume from the outer volume.
Mass Calculation: Multiplies the material volume by the specific density of the selected material.

The theoretical weight is calculated using the formula:
Weight = Volume × Density
where Volume = π × (R_outer² - R_inner²) × Length.

We use the following standard densities in our calculations:

Logistics: Accurately estimating shipping costs and truck load limits.
Structural Engineering: Ensuring supports and hangers are designed to hold the correct piping load.
Cost Estimation: Ordering the correct amount of raw material for fabrication projects.

Steel Pipe (Metric): A 6-meter length of standard steel pipe with 48.3mm OD and 3.68mm wall thickness weighs approximately 24.3 kg.
PVC Pipe (Imperial): A 10-foot length of PVC pipe with a 4-inch OD and 0.125-inch wall thickness can be easily estimated by switching to Imperial units.
