The Conversion Formula
To convert grams to kilograms, multiply the value by the conversion factor: 1 g = 0.001 kg. For a worked example, suppose you need to convert 25 g to kilograms: 25 × 0.001 = 0.025 kg. To convert in the opposite direction, divide by 0.001, or equivalently multiply by 1000.
About grams
The gram was the foundational unit of the original metric system in 18th-century France. Defined as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter (1 cm³), it brought logic to a chaotic world of measurements. It remains the standard for cooking, chemistry, and postal services. The gram is the base for the CGS system, which preceded the modern SI system. grams are commonly used in Cooking and baking ingredients, Nutritional labels (sugar, protein), Gold and jewelry, and Letter mail weights, Laboratory chemistry.

About kilograms
The kilogram (kg) is the base unit of mass in the International System of Units (SI). Established in 1795 as the mass of one liter of water at the freezing point, it has been the world's standard for over two centuries. Until 2019, it was defined by a physical platinum-iridium cylinder locked in a vault in Paris (Le Grand K). Today, it is defined by the Planck constant, a fundamental constant of quantum physics, ensuring it remains stable and precise forever. kilograms are commonly used in Body weight (worldwide except US), Gym equipment (plates/dumbbells), International shipping, and Scientific mass measurements, Food packaging (globally).
A liter of bottled water weighs exactly 1 kilogram.
