Yarn count converter
Metres and yards use 1 yd = 0.9144 m. A millimetre needle is matched to the nearest common US pairing below. Wraps per inch are reported as the number you measured. This page does not assign a yarn-weight class.

Common questions
Will wraps per inch name the yarn?
No. WPI is only the count you typed. The ball band and a gauge swatch name the yarn for your project. Craft Yarn Council weight ranges are guidelines, not a result of this form.
How is length converted?
Yards × 0.9144 = metres. Metres ÷ 0.9144 = yards.
