TL;DR (Too Long; Didn’t Read): 1,000 grams are in one kilogram.
When dealing with grams, kilograms, and other units of weight measurements, it is important to know the difference between weight and mass. These terms are often mixed up but refer to different things.
Mass is the amount of matter in an item, measured in grams and kilograms. These units of measurement are based on the metric system of measurement.
The gravitational force exerted on an object determines its weight.
Weight is determined by the gravitational force on an object. Here is a formula to help you understand the relationship between mass and weight:
Weight = Acceleration due to gravity x mass
Gravity is relatively the same anywhere on Earth, with slight variations due to altitude changes and centrifugal forces from the planet’s rotation.
However, the force of gravity changes if you are on the moon or Mars, for example. So, a person would technically weigh less on the moon than on Earth but have the same mass in both places. Mass does not change, but the weight can.
Summary: Mass does not change. It remains the same wherever you are. Weight depends on the acceleration due to gravity of the location. For example, in an environment without gravity, the weight of an object would be zero because there is no gravitational force exerted on the object.
The United States typically uses U.S. customary units of mass such as ounces, pounds, and tons. Almost everywhere else uses the metric system of measurements that uses grams, kilograms, and metric tons.
For quick reference, here is the conversion between different metric units of mass:
- 1,000 grams = 1 kilogram
- 1,000 kilograms = 1 metric ton
- 1,000,000 grams = 1 metric ton
Prefixes allow you to convey weight as fractions or multiples of a gram.
- 1 gigatonne (Gt) = 1,000,000,000,000,000 grams
- 1 megatonne (Mt) = 1,000,000,000,000 grams
- 1 tonne (t) = 1,000,000 grams
- 1 kilogram (kg) = 1,000 grams
- 1 gram (g) = 1 gram
- 1 milligram (mg) – 0.001 grams
- 1 microgram (µg) = 0.000001 grams
- 1 nanogram (ng) = 0.000000001 grams
- 1 picogram (pg) = 0.000000000001 grams

Seventeen countries signed the Treaty of the Meter on May 20, 1875, establishing international standards for length and mass. The treaty defined the kilogram as the official unit of mass.
In November 2018, the General Conference on Weights and Measures (CGMP) revised the definition of the kilogram.
Before the redefinition, a kilogram was defined as the exact mass of a platinum-iridium cylinder, known as the International Prototype of the Kilogram (IPK). The official IPK was stored in a vault just outside Paris. Prototypes were distributed to countries that signed the treaty.
Instead of basing the definition of a kilogram on a metal cylinder that kept on accumulating mass due to surface contamination, scientists decided to base the definition on a fundamental law of nature: the Planck constant.
Have you ever wondered what items weigh 1 kilogram? One kilogram is 2.20462 pounds. Here's a short list of things that weigh about 1 kilogram.
- A pineapple
- A cabbage
- 400 pennies

- 176 quarters
- 88 half dollars
- 123 dollar coins
By comparison, items that weigh one about 1 gram include a paper clip, a U.S. dollar bill, a piece of chewing gum, a Bic brand pen cap, and a Japanese yen coin.
The most accurate way to measure grams and kilograms is to use a scale. When baking or cooking, you may use spoons and kitchen cups, but these measuring tools will only provide an approximate value. For best results, use a kitchen scale to measure grams and kilograms.
Select a mechanical or digital scale that operates with metric units of measurements. Place an empty container on the scale and then apply the tare function to remove the weight of the container.
If your scale does not have a tare function, subtract the weight of the container from the final amount when all the ingredients are in the container. Place items you are measuring inside the container and read the number on the digital display.
To measure with cups and spoons, you will need measuring tools that measure in grams, which may also have milliliter conversions. Some glass measuring cups may have grams listed as well. Fill the measuring tool with the ingredient and scrape the excess from the top.
To measure grams and kilograms of a known mass value, you can use a couple of formulas. Multiply the number of kilograms by 1,000 to get the gram conversion since 1,000 grams is 1 kilogram. You can also convert grams to kilograms by dividing the number of grams by 1,000.
