The conventional gauge spans are close but not exactly equal: four inches is 10.16 cm. Keep the stated measuring span when precision affects fit.

## 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

Twenty stitches over 10 cm correspond to 20.32 over 10.16 cm. Do not round this intermediate rate to a whole stitch before calculating a much wider garment.

## 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.
