When to convert g to lb

• ▸Body weight tracking — bathroom scales, BMI calculators and airline check-in all mix g and lb; 247710 g is the value you enter, lb is what the app stores.
• ▸Gym & powerlifting — plates are labelled in g in US gyms and lb in European gyms; a 247710 g lift is the same load, different label.
• ▸Cooking & baking — recipes from the US use g while European recipes use lb; 247710 g of flour = the lb value your kitchen scale shows.
• ▸Shipping & parcel weight — courier calculators (FedEx, DHL, USPS) accept either unit; entering the wrong one can double your shipping cost.
• ▸Medicine dosing — drug doses are calculated per kg; if your weight is in g, converting to lb is often the first step.

Common mistakes

• ✕Confusing pounds (lb) with pound-force or with the British stone (1 st = 14 lb).
• ✕Rounding too aggressively — 1 lb = 0.4536 kg, not 0.45 kg; the error compounds on large weights.
• ✕Using US "cups" for solid weight — cups are a volume unit, not a mass unit.
• ✕Short ton, long ton and tonne are three different units. A US short ton is 2000 lb = 907.18474 kg. A UK long ton is 2240 lb = 1016.0469088 kg. A metric tonne is 1000 kg. Freight and commodity figures are wrong by up to 12% if these are mixed up.
