Kilograms to pounds on a scale that only speaks one language
Kitchen scales in grams, airline desks in kilograms, US gyms in pounds. The avoirdupois pound is 0.45359237 kg exactly, so kilograms to pounds is divide by that — or multiply by about 2.20462.

Body weight and plates
70 kg is about 154.3 lb. 20 kg plates are 44.1 lb, not a clean 45. If the gym’s 45s are US plates, they are 20.41 kg. Do not mix a “20 kg” bar math with 45 lb plates and expect the spreadsheet to match the floor.
Shipping labels that say 2 kg are 4.41 lb. Carriers still round up to the next half-pound in their own tables — convert first, then read their chart.
Stone and troy are other dictionaries
UK stone is 14 lb. Troy ounces are for bullion, not body weight. Use those pages when the document says stone or troy. This kilogram–pound pair is avoirdupois.
Key takeaways
- kg × 2.20462 ≈ lb. The pound is defined from the kilogram.
- Gym “45s” and “20 kg” plates are not the same disk.
- Stone and troy are different pages.
