Weight Formula For Steel
1. Coil Weight Calculator
Formula:
Weight (lbs) = (OD2 - ID2) × k × Width × π
Where:
- OD: Outer Diameter (inches)
- ID: Inner Diameter (inches)
- Width: Width (inches)
- k = 0.0711 (Material density coefficient)
Example Calculation:
Given:
OD = 12 inches
ID = 9 inches
Width = 1 inch
Calculation:
Weight = (122 - 92) × 0.0711 × 1 × π
Weight ≈ 14 lbs
2. Coil Weight Per Circle
Formula:
Weight (lbs) = Diameter2 × Gauge × π × k
Where:
- Diameter: Diameter (inches)
- Gauge: Thickness (inches)
- k = 0.0711 (Material density coefficient)
Example Calculation:
Given:
Diameter = 15 inches
Gauge = 2 inches
Calculation:
Weight = 152 × 2 × π × 0.0711
Weight ≈ 100.5 lbs
3. Maximum Coil OD
Formula:
OD = ID + k × (Weight / Width) + c × Width
Where:
- ID: Inner Diameter (inches)
- Width: Width (inches)
- Weight: Weight (lbs)
- k = 0.173
- c = 0.007
4. Flat Sheet Weight
Formula:
Weight (lbs) = Thickness × Width × Length × k
Where:
- Thickness: Thickness (inches)
- Width: Width (inches)
- Length: Length (inches)
- k = 0.284 (Material density coefficient)
5. Coil Lineal Feet
Formula:
Length (ft) = (Weight × k) / (Thickness × Width)
Where:
- Thickness: Thickness (inches)
- Width: Width (inches)
- Weight: Weight (lbs)
- k = 0.29342723 (Conversion coefficient)
6. Coil Feet to Weight
Formula:
Weight (lbs) = Thickness × Width × Length × k
Where:
- Thickness: Thickness (inches)
- Width: Width (inches)
- Length: Length (feet)
- k = 3.408 (Material density coefficient)
Note: Ensure all input parameters are in consistent units to avoid calculation errors.
