Wraps per inch (WPI) ↔ yarn weight category
Convert wraps per inch (WPI) count to standard yarn weight categories, and find recommended knitting needle/crochet hook sizes.
Twist per inch (TPI) — spinning wheel flyer ratio ↔ speed
Calculate twists per inch (TPI) based on flyer ratio, treadles per minute, and fiber intake rate.
Fiber preparation — raw fleece weight ↔ washed clean yield
Estimate washed clean fiber yield, grease/lanolin loss weight, and clean weight from raw animal fleeces by breed.
Roving weight ↔ finished yarn yardage estimate
Calculate expected yarn yardage from roving mass based on target spinning grist (yards per pound or run).
Plying angle ↔ yarn strength — twist balance
Calculate optimal twist plying angles, yarn twist multipliers, and balance criteria to spin stable structured yarns.
