A focused calculator: enter your project dimensions, get exact tonnage — directly usable for purchase orders.
How Tonnage Is Calculated
- Compute volume: length × width × thickness
- Compute weight: volume × 145 lbs/ft³ (or 2,322.7 kg/m³)
- Convert: divide by 2,000 (US short tons) or 1,000 (metric tonnes)
- Add 10% buffer (recommended)
