In practice
Kilograms to grams multiplies by 1,000, because a kilogram is exactly a thousand grams. It is the conversion for cooking from bulk packs, post and parcel weights, and fitness tracking. A 1.5 kg bag of sugar is 1,500 g, and a 2.25 kg joint of beef is 2,250 g, which is the number to use when scaling a recipe or setting a kitchen scale. Remember that scales in grams are more precise for baking than volume measures, so converting up front usually improves the result.
