What formula is used to calculate pipe weight?

Weight = (OD - Wall Thickness) × Wall Thickness × π × Length × Density. This computes the volume of the pipe wall and multiplies by the material density.

Which stainless steel grades are supported?

The tool supports SS 304 (7930 kg/m³), SS 316 (7980 kg/m³), SS 321 (7900 kg/m³), SS 310 (7950 kg/m³), and SS 430 (7700 kg/m³).

How much does 304 stainless steel weigh?

Type 304 stainless steel has a density of about 7,930 kg/m³ (0.286 lb/in³). As an example, a 1-inch Schedule 40 304 pipe weighs about 2.5 kg per metre (1.7 lb per foot).

Can I use this for other metals?

This calculator is specifically tuned for stainless steel grades. For carbon steel or other alloys, the densities differ and you would need a different tool.

What is wall thickness and how do I find it?

Wall thickness is the radial distance between the outer and inner surface of the pipe. It is listed on pipe schedules (e.g., SCH 10, SCH 40) or stamped on the pipe itself.

Does this account for pipe schedule standards?

The calculator uses raw dimensions you enter. To use a schedule, look up the OD and wall thickness for your nominal pipe size and schedule, then enter those values.

Is the result in weight or mass?

The result is mass (kg or lb). In everyday usage this is commonly called "weight." True weight (force) would be mass × gravitational acceleration, but mass is the standard for material ordering.
