The 20 kg and 45 lb versions aren't quite the same: 20 kg is 44.1 lb, and a true 45 lb bar is 20.4 kg. Most US "45 lb" bars are really 20 kg bars rounded up, which is fine for training.

How to find out what your bar weighs

  1. Read the end cap or sleeve. Most quality bars print the weight there.
  2. Look up the model. Manufacturers list exact weights.
  3. Weigh it. Stand on a scale holding the bar, then without it, and subtract.

Once you know, set it in the plate calculator under Bar (or Custom) and every total comes out right.

Does the bar weight count?

Yes. The weight you lifted is the bar plus everything on it, so a 45 lb bar with one 45 lb plate on each side is 135 lb. More on that in does the bar count.
