I've played the pack and repack game before, made weight in kilogram measurement but was a few ounces over in pounds measurement in America when I had to recheck my bags after customs. It was either that, or pay a $50 charge, why wouldn't I move a couple shirts from my checked bag into my carryon
If you ever want to see some fun check-in counter arguments, watch the check-in counter for some of the African flights, where people only go home once a year or less and are trying to bring stuff back for their families. Watched one lady trying to fly with a 75kg regular sized suitcase, I still wonder what she had packed in there

I carry a luggage scale. And I set it for the units that the airport is using, pounds or kg. I assume that their scale is off to benefit them a bit and I assume that my scale is off because I am really cheap and buy the cheapest scale. Thus, I aim for 49 pounds if the limit is 50 and aim for 22.5 kg when the limit is 23. I have a few luggage scales, all read almost exactly the same (within a few tenths of a percent). But half the time I find that my 49 pound bag is 50 pounds on the airline scale.
Some heavy stuff that is small, like pedals I often put in my carry on to take weight out of the checked bag or bike case/box.
My expedition bike and the S&S case combined are over 50 pounds, so I have to carry a few bike parts in other bags to get the packed bike lower in weight.
