Weight is measured metrically in tonne, kilogram, gram and milligram, and in the Anglo-American world in pound and ounce. When cooking from international recipes, shipping parcels or reading product details you often need to convert between these units. This converter takes a value in one unit and gives it in another.
The basis is the international definition: one pound (lb) is exactly 453.59237 grams and one ounce (oz) exactly 28.349523125 grams. Note: the colloquial German Pfund means 500 grams and is something different from the international pound used here. Internally your value passes through the base unit gram, so any combination is possible.
Strictly speaking physics distinguishes between weight as a force and the amount of matter a scale actually determines - in everyday use the two are treated alike, and this calculator converts between the units as you would normally expect. The calculation runs entirely locally in your browser in pure JavaScript; nothing is uploaded or stored. The display rounds to six decimals.
