Common real-world scenarios where this tool saves time.
International travellers and expats
A 15 kg luggage limit on a European airline means 33 lb. A 50 lb gym dumbbell is 22.7 kg. Quick weight conversion removes the guesswork when switching between metric and imperial countries.
Cooks and bakers
Professional recipes from different countries use different weight units. Gram-precise baking conversions ensure consistent results for pastry and bread recipes.
E-commerce sellers and shippers
International couriers (FedEx, UPS, DHL) accept weights in kg or lb depending on origin country. Convert package weights to avoid billing errors.

1 kilogram = 2.20462 pounds (exact to 5 decimal places). The commonly-used approximation is 1 kg ≈ 2.2 lb. For body weight: 70 kg = 154.3 lb, 80 kg = 176.4 lb, 100 kg = 220.5 lb.
1 ounce (avoirdupois) = 28.3495 grams. The kitchen shortcut is 1 oz ≈ 28 g. Note: troy ounces (used for precious metals) = 31.1035 g — heavier than the regular ounce.
1 stone = 14 pounds = 6.35029 kg. Stone is used almost exclusively in the UK and Ireland for human body weight. 11 stone = 154 lb = 69.85 kg. Most of the world uses kg; the US uses lb exclusively.
16 ounces = 1 pound. This is the avoirdupois system used for everyday goods. Note: the troy system (used for gold, silver, gems) has 12 troy ounces per troy pound — different from the standard avoirdupois pound.
In everyday use, 'weight' usually means mass (the amount of matter in an object). In physics, weight is a force (mass × gravitational acceleration). A 70 kg person has a weight of 686 newtons on Earth but 113 newtons on the Moon — the mass stays the same. Conversion tools deal with mass.
