The kilogram (kg) is the SI base unit of mass, used almost everywhere, while the pound (lbs) is the avoirdupois unit of the US customary and imperial systems. Travelers hit this conversion at airline check-in, and it is just as common for body weight, gym equipment, and shipping paperwork that crosses between metric and US units.
One kilogram equals 2.20462 lbs, so a 23 kg checked-bag limit is 23 × 2.20462 = 50.7 lbs — which is why US airlines quote the same allowance as 50 lbs. For mental math, double the kilograms and add 10%: 23 doubles to 46, plus 4.6 gives 50.6 lbs, within about 0.2% of the exact value.
