This page has an interactive calculator and some of the formulae to use.
However, there are differences based on the exercise itself. Here is another chart to show a different conversion factor for squat, bench press & deadlift.
| Repetitions | Squat | Benchpress | Deadlift |
|---|
| 1 | 1.0 | 1.0 | 1.0 | | 2 | 1.0475 | 1.035 | 1.065 | | 3 | 1.13 | 1.08 | 1.13 | | 4 | 1.1575 | 1.115 | 1.147 | | 5 | 1.2 | 1.15 | 1.164 | | 6 | 1.242 | 1.18 | 1.181 | | 7 | 1.284 | 1.22 | 1.198 | | 8 | 1.326 | 1.255 | 1.232 | | 9 | 1.368 | 1.29 | 1.232 | | 10 | 1.41 | 1.325 | 1.24 |

Will post when I try!
