Working with both inches and centimeters means converting a lot of fractions to decimals. I have better things to remember than these conversions, so I wrote them out. I didn’t include the obvious ones like 1/4 (.25) or 1/2 (.5) because I know them so well already. Below are the most commonly used fractions I convert into decimals. The fractions are all denominators of 16 (since inches are typically divided that way), and the fractions are rounded to the thousands place.
| FRACTION | DECIMAL |
|---|---|
| 1/16 | .063 |
| 1/8 (2/16) | .125 |
| 3/16 | .188 |
| 5/16 | .313 |
| 3/8 (6/16) | .375 |
| 7/16 | .438 |
| 9/16 | .563 |
| 5/8 (10/16) | .625 |
| 11/16 | .688 |
| 13/16 | .813 |
| 7/8 (14/16) | .875 |
| 15/16 | .938 |
