Kilograms to Grams Converter
Convert kilograms to grams and grams to kilograms instantly. Whether you're cooking, doing science homework, or measuring ingredients, this free weight converter gives you fast, accurate results every time.
What Is a Kilogram?
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is defined by the Planck constant and is approximately equal to the mass of one liter of water. The kilogram is the most widely used unit of mass in the world, used for everything from measuring body weight to weighing groceries and industrial materials.
The gram (g) is a smaller unit of mass in the metric system, equal to one-thousandth of a kilogram (0.001 kg). Grams are commonly used for smaller measurements like cooking ingredients, jewelry, and laboratory measurements.
How Does the Kilograms to Grams Converter Work?
The converter uses the exact metric conversion factor:
1 kg = 1,000 g
To convert kilograms to grams:
grams = kilograms × 1,000
To convert grams to kilograms:
kilograms = grams ÷ 1,000
Simply enter a value in either kilograms or grams, select the conversion direction, and the calculator will instantly display the result. The converter also shows the equivalent weight in pounds and ounces for your convenience.

What is the difference between a kilogram and a gram?
A kilogram is the base unit of mass in the metric system. A gram is a smaller unit equal to one-thousandth of a kilogram (0.001 kg). Grams are used for smaller measurements, while kilograms are used for larger weights.
How many grams are in 2 kilograms?
2 kilograms × 1,000 = 2,000 grams.
How many grams are in 0.5 kilograms?
0.5 kilograms × 1,000 = 500 grams.
How many kilograms are in 1,000 grams?
1,000 grams ÷ 1,000 = 1 kilogram.
How many kilograms are in 500 grams?
500 grams ÷ 1,000 = 0.5 kilograms.
What is the symbol for kilogram?
The symbol for kilogram is kg. The symbol for gram is g.
Is a kilogram heavier than a gram?
Yes. A kilogram is 1,000 times heavier than a gram. 1 kg = 1,000 g.

What is the difference between mass and weight?
Mass is the amount of matter in an object, measured in kilograms or grams. Weight is the force of gravity on that mass, measured in newtons or pounds-force. In everyday use, the terms are often used interchangeably.
Is the kilogram still defined by a physical object?
No. Since 2019, the kilogram has been defined by the Planck constant using a Kibble balance. It is no longer defined by a physical artifact (the International Prototype Kilogram).
How do I use this calculator for cooking?
Many recipes use grams for precise measurements. Enter the weight in kilograms (or grams) and the calculator will convert it to the unit you need. For example, 0.25 kg = 250 g.
