Yarn length converter

Convert yarn-label lengths between metres, international yards and feet.

Use a single decimal point or comma, without thousands separators or unit symbols. All lengths use the selected unit. Values must be 0–1,000,000; dimensions and swatch counts must exceed zero. Counts must be whole numbers. Extra allowance: 0–100%; lengthwise shrinkage: 0–50%.

Assumptions & limits

This converts length only. It cannot convert yarn weight to length or predict whether a substitute yarn has the same thickness, fibre, gauge or behaviour. Check the ball label and swatch before substituting.

Formula

output = input × source factor ÷ target factor; 1 yd = 0.9144 m; 1 ft = 0.3048 m

Worked example

1000 yd = 914.4 m; 300 ft = 100 yd.

Results show up to 8 decimal places. Small values use scientific notation; calculations use unrounded factors.
