1 gram = 0.001 kg
Conversion formula
kilograms (kg) = grams (g) × 0.001
How to convert g to kg?
To convert grams (g) to kilograms (kg), one must understand the relationship between these two units of mass in the metric system.
A gram is defined as one-thousandth of a kilogram, meaning 1 gram equals 0.001 kilograms. Consequently, to convert a mass from grams to kilograms, you divide the number of grams by 1,000. Mathematically, this is represented as:
mass in kilograms = mass in grams / 1000
Example
- kilograms (kg) = grams (g) × 0.001
- kilograms (kg) = 87 (g) × 0.001
- kilograms (kg) = 0.087
- mass in kilograms = mass in grams / 1000
- mass in kilograms = 87 / 1000
- mass in kilograms = 0.087
How many kilograms in a gram?
Conversely, to determine how many kilograms are in a gram, we use the same relationship. Since 1 gram is 0.001 kilograms, this indicates that each gram is a thousandth of a kilogram. Understanding this conversion is essential in various scientific and everyday contexts, such as measuring ingredients in cooking or calculating dosages in medicine, where precise mass measurements are crucial.

About Grams
Definition gram
The gram (g) is a unit of mass in the International System of Units (SI), defined as one-thousandth of a kilogram.
This means that 1 gram equals 0.001 kilograms. It serves as a fundamental unit for measuring mass, especially in contexts requiring precision and smaller quantities.
History unit gram
The term "gram" originates from the Late Latin "gramma," meaning a small weight.
In 1795, during the French Revolution, the gram was officially defined as the mass of one cubic centimeter of water at the melting point of ice. This definition was part of an effort to create a standardized system of measurements. Over time, the definition evolved, and in 1960, the gram was redefined as one-thousandth of a kilogram when the International System of Units (SI) was established.
Current Use
Today, the gram is widely used around the world for measuring non-liquid ingredients in cooking and grocery shopping.
It's also commonly used in science and engineering to measure mass. In many countries, nutrition labels on food products require contents to be stated per 100 grams, providing a standardized way to convey nutritional information.

About kilogram
Definition kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI), defined by setting the Planck constant to exactly 6.62607015×10⁻³⁴ joule seconds (Js).
This definition, established in 2019, links the kilogram to fundamental constants of nature, ensuring long-term stability and precision in mass measurements.
History
Introduced during the French Revolution, the kilogram was initially defined in 1795 as the mass of one cubic decimeter of water at the melting point of ice.
Due to challenges in precise measurement, it was later redefined in 1889 based on a platinum-iridium prototype known as the International Prototype of the Kilogram (IPK). In 2019, to eliminate reliance on a physical object, the kilogram was redefined using the Planck constant.
Current Use
Today, the kilogram is universally employed as the standard unit for mass in science, industry, and commerce. It serves as the foundation for measuring weight and mass globally, ensuring consistency and accuracy across various fields, from laboratory research to everyday transactions.
