Sixteenths → decimal (inches)
| Fraction | Decimal |
|---|---|
| 1/16" | 0.0625 |
| 1/8" | 0.125 |
| 1/4" | 0.25 |
| 1/2" | 0.5 |

Many US tapes mark eighths and sixteenths. Converting to decimals helps CAD; converting to fractions helps field layout. Use both paths without losing the inch as the common anchor.
