| Bar | Plates per side | Per side |

100 lb = 45.4 kg. Kilo and pound plates are not interchangeable, so in a metric gym the exact equivalent weight usually cannot be loaded.
If this is a working weight, here is what it represents at a few common maxes.
| Your 1RM | % of 1RM |
|---|---|
| 225 lb | 44 % |
| 275 lb | 36 % |
| 315 lb | 32 % |
| 365 lb | 27 % |
| 405 lb | 25 % |
The app does this in both directions: enter a weight and get the plates, or tap the plates already on the bar and get the weight.
