For one uniform yarn, estimate length from net remaining mass and the original length-to-mass ratio. Remove packaging and keep uncertainty from scale resolution visible.

## Before you start

Gather the measurements, counts or timing sample needed below. Record their units and whether they describe a sample, the whole project or one purchased package. Use a finished sample when dimensions or material use depend on fabric structure.

## Try this example

A 200 m/50 g yarn has about 4 m per gram. A net 18 g remainder suggests 72 m before damaged ends; a 1 g weighing difference changes the estimate by 4 m.

## Check your result

- Recheck the inputs against the actual sample or label, keep units consistent and round only the final count or purchase. Repeat a sample if a small measuring difference changes the decision.
- These arithmetic examples assume the measured structure stays comparable. Shaping, borders, dense textures and color changes require their own allowances or samples.
