Aluminum Coil Calculators

Default 0.099 lb/in³ (Aluminum).
Selecting a gauge will auto-fill thickness (t) fields below.

1) Coil Weight

Given outer diameter (OD), inner diameter (ID) and width (W), estimate coil weight in pounds.

Weight
— lb
PIW (Weight ÷ W)
— lb/in
Metric: —

Formula: W = ρ × (π/4) × (OD² − ID²) × Width

2) Coil Weight Per Circle (one wrap)

Given diameter (D), thickness/gauge (t), and width (W), estimate the weight per wrap.

Weight per wrap
— lb
Per-wrap PIW (Wrap ÷ W)
— lb/in
Metric: —

Formula: W = ρ × (π × D) × (t × W)

3) Maximum Coil OD

Given ID, width and total weight, compute the maximum OD. Also shows PIW.

Max OD
— in
PIW (Weight ÷ W)
— lb/in
Metric: —

Formula: OD = √[ ID² + 4 × Weight / (π ρ W) ]

4) Flat Sheet Weight

Given thickness, width and length, estimate sheet weight. Enter length in inches, or in feet and we’ll convert.

Sheet Weight
— lb
PIW (Weight ÷ W)
— lb/in
Metric: —

Formula: W = ρ × t × W × Lin (where Lin = 12 × Lft)

5) Coil Lineal Feet

Given thickness, width and total weight, estimate feet of material.

Lineal Feet
— ft
PIW (Weight ÷ W)
— lb/in
Metric: —

Formula: Feet = Weight / (12 × ρ × t × W)

6) Coil Feet → Weight

Given thickness, width and feet, estimate total weight.

Total Weight
— lb
PIW (Weight ÷ W)
— lb/in
Metric: —

Formula: Weight = 12 × ρ × t × W × F

Notes: Inputs are Imperial (inches, feet, pounds). Calculations assume ideal geometry and constant density. Consider tolerances and scrap for quoting.
