Understanding Weight and Mass Units

Weight and mass are often used interchangeably in everyday language, though they differ in physics. For practical purposes—cooking, shipping, health—we convert between units like kilograms, pounds, ounces, and grams. Americans use pounds and ounces; most of the world uses kilograms and grams. A 2 kg package is about 4.4 lbs. A recipe calling for 500 g flour needs about 17.6 oz. Converting correctly matters for recipes, shipping costs, and health tracking. Our converter handles kg, lbs, oz, g, and more. Enter any value, get instant conversion. See Unit of mass on Wikipedia for the full picture.

Common Weight Units

Kilograms (kg): The metric standard. 1 kg = 1,000 g. Used worldwide for body weight, produce, and packages. A person might weigh 70 kg (about 154 lbs).

Pounds (lbs): Used in the US and UK. 1 lb ≈ 0.454 kg. Common for body weight, produce, and shipping in imperial regions.

Ounces (oz): 1 lb = 16 oz. Used for smaller quantities—food portions, mail, ingredients. 1 oz ≈ 28.35 g.

Grams (g): 1/1000 of a kilogram. Common for cooking, nutrition labels, and small items. 100 g ≈ 3.5 oz.
