When to convert lb to oz

  • ▸Body weight tracking — bathroom scales, BMI calculators and airline check-in all mix lb and oz; 304609 lb is the value you enter, oz is what the app stores.
  • ▸Gym & powerlifting — plates are labelled in lb in US gyms and oz in European gyms; a 304609 lb lift is the same load, different label.
  • ▸Cooking & baking — recipes from the US use lb while European recipes use oz; 304609 lb of flour = the oz 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 lb, converting to oz 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.

Regional usage & source

Kilograms and grams are the global standard for mass. Pounds and ounces remain common in the US. The UK still uses stone (1 st = 14 lb) for body weight in everyday speech.

Reference: 1 pound (avoirdupois) = exactly 0.45359237 kilograms per the 1959 international yard and pound agreement (NIST Handbook 44).
