*Note. Powerlifting (PL) and weightlifting (WL) have plates that feature the same weight from 25kg down to 2.5kg. The change plates differ slightly as weightlifting requires a 1kg increase to set a new record, while powerlifting only requires a 0.5kg increase. Therefore, weightlifting change plates, lighter than 2.5kg, differ slightly from powerlifting change plates.
Weightlifting: 2 kg (blue), 1.5 kg (yellow), 1 kg (green) and 0.5 kg (white).
Powerlifting: 1.25 kg,, 0.5 kg, 0.25 kg (all chromed).
This may cause issues when you try to load a total weight that does not conform to weightlifting record standards.e.g 103kg will need 25x1, 10x1, 2.5x1, 1.5x1. But 103.5kg, with a 0.5kg increase, is not "regulation" so the plate list will show a remainder not loaded on the bar. This is not an issue with powerlifting.
And in case you were wondering, both disciplines are metric. The third option of "Mix of lb & kg" is for use in a gym which is unfortunately burdened with 45kg plates but where you have your own change plates from 5kg down to the either 0.5kg (WL) or 0.25kg (PL).
