This is the approximate filament length for the entered weight.
What this estimate includes
The calculation treats filament as a solid cylinder. It is useful for comparing spool labels, planning stock and translating slicer estimates. Actual spool length can vary with diameter tolerance, density, additives and manufacturer specification. Use the value printed on your spool when it differs.
