📖 How to Use

📦 Roll → SheetEnter the roll weight, GSM, and roll width. Optionally add a sheet length to see how many sheets you can get.
⚖️ WeightEnter roll length, width and GSM to calculate the total weight in kg.
💰 CostEnter the price per ton, GSM, and sheet dimensions to calculate the cost per sheet.
Formulas used:
Roll Length (m) = Weight (kg) × 1,000,000 ÷ (GSM × Width (mm))
Sheets = Roll Length (m) × 1000 ÷ Sheet Length (mm)
Sheet Weight (g) = GSM × Width (m) × Length (m)
