Calculation Method
- Reel mode: spiral winding geometry, layer-by-layer summation
- Each layer circumference = π × (core_OD + cable_OD × (2i+1))
- Packing efficiency accounts for real-world winding gaps
- Weight mode: total weight = length × weight_per_meter × quantity
Accuracy Notes
- Reel results: typical accuracy ±5–10%
- Actual winding may not be perfectly uniform
- For precise inventory, direct measurement is recommended
- Weight values from standard cable datasheets (IEC 60228)
Typical Use Cases
- Estimating remaining cable on partial reels
- Procurement and logistics weight planning
- Checking if a reel has enough cable for a run
- Shipping and transport load calculations
