Aidez-nous ! J'ai un patron avec des tailles américaines, comment puis-je le convertir ?
| Imperial to metric | Metric to imperial |
| 1/4 yard = 23cm | 10 cm = approx. 4" |
| 1/3 yard = 30.6cm | 0.5 m = 50cm = approx. 19" |
| 1/2 yard = 46cm | 90 cm (width of most Vlieseline interfacing) = 1 yard / 36" |
| 1 yard = 92cm | 1 m = 100cm = approx. 40" |
| 43" = 110cm | 140 cm (width of most fabrics / faux leather) = 55" |
For hardware these are the most frequently used sizes.
