The 45 lb plate is actually a compromise - it's very close to 20 kg (44.09 lbs), which is the international standard. When Olympic lifting became popular, equipment manufacturers made plates that worked for both systems. Similarly, a '35 lb' plate is really 15 kg (33.07 lbs).

Divide pounds by 2.2 for a quick estimate. For more accuracy, divide by 2 and subtract 10%. Example: 180 lbs ÷ 2 = 90, minus 9 (10%) = 81 kg. The actual answer is 81.65 kg, so you're within 1%.

Weight-based dosing accounts for body size differences, ensuring therapeutic effectiveness while minimizing toxicity. A dose safe for a 50 kg person might be ineffective for someone weighing 100 kg, or toxic for someone weighing 25 kg. This is especially critical in pediatrics.

Pound-mass (lbm or just lb) measures mass/weight. Pound-force (lbf) measures force. On Earth's surface, 1 lbm weighs 1 lbf, but they're different units. In engineering, this distinction matters for calculations involving acceleration. Most everyday uses mean pound-mass.

Yes! Overweight baggage fees can be substantial. US airlines typically charge for bags over 50 lbs (22.68 kg), but international carriers use 23 kg (50.71 lbs). That 0.71 lb difference could trigger an overweight fee if you packed exactly 50 lbs thinking you were safe.
