Converting is the easy half. 102.5kg is 225.97lb, and nobody has ever loaded 225.97lb. This tells you the nearest weight you can actually put on the bar, on the bar you are actually using, and exactly what that costs you.
Competition kit and drawn to scale? Powerlifting or weightlifting.
Why this is not just times 2.2.
A conversion is exact and a barbell is not. 1kg is 2.20462262 lb, so 102.5kg is 225.97lb. That number is correct and you cannot load it. What you can load, on a 45lb bar with a normal American rack, is 225lb, and that is 0.44kg lighter than your programme asked for. Knowing the gap is the point. Rounding it away silently is how a top set drifts.
The bar is part of the answer. An Olympic bar is 20kg in a kilo gym and 45lb in a pound gym, and those are not the same bar: 45lb is 20.41kg. A women's bar is 15kg or 35lb. A trap bar is anywhere from 20kg to 32kg depending on the make, which is why there is a box to type your own. If a calculator assumes 20kg it is quietly wrong for most of what an S&C athlete actually picks up.
Plates come in pairs. Everything here is per side and doubled, so an odd leftover is reported rather than hidden. If your gym stops at 1.25kg or 2.5lb, the nearest loadable weight steps in 2.5kg or 5lb, and this says so instead of pretending otherwise.
The drawing is indicative, not to scale, and that is the difference between this page and the other two. Their figures are Eleiko's published measurements for a standardised competition kit, so a plate's width on screen is its real thickness. Nobody publishes a figure for "a gym": one rack's 20kg is cast iron 25mm thick and the next one's is a 50mm rubber bumper. So diameters here follow the usual tapering and thickness follows weight, which is enough to recognise a loading at a glance and not enough to measure with. That is also why there is no sleeve capacity warning here and there is one on the other two: guessing at the point where a sleeve runs out would be inventing a number you might plan a session around.
Kilo racks here are the usual UK commercial set: 25, 20, 15, 10, 5, 2.5 and 1.25. Pound racks are 45, 35, 25, 10, 5 and 2.5. Neither is a competition set, and for calibrated steel drawn to scale use the powerlifting page or the weightlifting one.
A converter tells you what a number is. It does not tell you whether that number should be on the bar this week. Training maxes is where the ones that should come from.
