Frequently Asked Questions

How do I convert kilograms to grams?

Multiply the kilogram value by 1,000. For example, 0.5 kg × 1,000 = 500 g.

How many grams are in a kilogram?

Exactly 1,000 grams, since "kilo" is the SI prefix for one thousand.

Why do recipes sometimes list ingredients in grams instead of kilograms?

Grams give more useful precision for the smaller quantities typical in a single recipe; kilograms become more practical once quantities scale up, such as in bulk cooking or commercial baking.

Recommended

A good measuring tool marked in both kg and g removes the guesswork at the point of use.
