# Galvanized Coil & Sheet Calculations

Calculation for Determining Average Decimal of Coil/Sheet

• Coil: Scale weight (actual weight) divided by 40.8 divided by Width of Coil in Feet divided by Linear Footage.
• Sheet: Net weight (less dunnage) or actual weight of skid divided by 40.8 divided by square feet of sheet divided by sheet count.

Calculation for Total Square Footage

• Coil: Width in Feet X (times) Linear Footage.
• Sheet: Length in inches X (times) width in inches divided by 144 X (times) sheet count.
• Sheet: Length in feet X width in feet X sheet count.

Calculation to Convert Zinc Coatings

 Zinc Coatings- How to Convert 1 oz/ft2 = 305.15 g/m2 To convert from oz/ft2 to g/m2, multiply by 305.15 Example: G90 (0.90 oz/ft2) = Z275 (275 g/m2)
