Where you'll actually use this

Weight (technically mass) measures how much matter an object contains. The kilogram anchors the metric system, while pounds and ounces dominate everyday use in the United States.

  • Shipping & freight

    Postage, courier rates, and pallet weights swap between kg and lb depending on carrier and destination country.

  • Cooking & baking

    Precise recipes — especially European baking — call for grams instead of cups or ounces for repeatable results.

  • Fitness & nutrition

    Body weight, protein intake, and gym plates often need conversion between metric and imperial.

  • Travel luggage

    Airline weight limits are quoted in kilograms internationally but in pounds for many US domestic carriers.

Common mistakes to avoid

  • Confusing mass and weight

    Mass is constant; weight depends on gravity. On Earth they're proportional, so converters treat them interchangeably.

  • Short ton vs metric ton

    A US (short) ton is 2,000 lb ≈ 907 kg. A metric ton is exactly 1,000 kg ≈ 2,205 lb.

  • Stone equals 14 pounds

    Body weight in the UK is often given in stone — 11 st 4 lb means 158 lb, not 11.4.

Did you know?

The kilogram is now defined by Planck's constant

In 2019 the kilogram stopped being defined by a physical platinum-iridium cylinder and switched to a fixed value of Planck's constant.

An ounce isn't always 28 g

A troy ounce — used for precious metals — is about 31.1 g, around 10% heavier than the everyday avoirdupois ounce.
