TL;DR (Too Long; Didn’t Read): 1,000 grams are in one kilogram.

Mass and Weight: Defined

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.

What Is Mass?

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.

What Is Weight?

The gravitational force exerted on an object determines its weight.

The Relationship Between Mass and 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. 

What Are Metric Units of Weight?

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

Converting Pounds to Grams

One pound is equal to 453.5923 grams. 

To convert pounds to grams, multiply the number of pounds by 453.5923. For example, to determine the number of grams in 10 pounds, multiply 10 by 453.5923.

10 pounds x 453.5923 = 4,535.923 grams

Converting Pounds to Kilograms

One pound is equal to 0.4535923 kilograms.

To convert pounds to kilograms, multiply the number of pounds by 0.4535923. For example, to determine the number of kilograms in 10 pounds, multiply 10 by 0.4535923.

10 pounds x 0.4535923 = 4.535923 kilograms

For an approximate result, you can also divide the mass value by 2.205

10 pounds ÷ 2.205 = 4.53514739229 kilograms

Converting Ounces to Grams

One ounce is equal to 28.3495 grams.

To convert ounces to grams, multiply the number of ounces by 28.3495. For example, to determine the number of grams in 5 ounces, multiply 5 by 28.3495.

5 ounces x 28.3495 = 141.7475 grams

Converting Ounces to Kilograms

One ounce is equal to 0.0283495 kilograms.

To convert ounces to kilograms, multiply the number of ounces by 0.0283495. For example, to determine the number of kilograms in 12 ounces, multiply 12 by 0.0283495.

12 ounces x 0.0283495 = 0.340194 kilograms

You can also divide the mass value by 35.274.

12 ounces ÷ 35.274 = 0.34019391052 kilograms

What Is a Gram?

Merriam-Webster defines a gram (g or gm) as a “metric unit of mass equal to 1/1000 kilogram and nearly equal to the mass of one cubic centimeter of water at its maximum density.”

In the United States, ounces and pounds are more commonly used than grams. Food product labels will feature grams on the nutrition label.

Grams refer to units of mass. One-thousand grams equals one kilogram or about 2.2 pounds.

What Is a Kilogram?

Merriam-Webster defines a kilogram (kg) as “the base unit of mass in the International System of Units that is defined by setting the fixed numerical value of Planck’s constant to 6.62607015 x joule seconds.”

A kilogram is a unit of mass for the metric system. One gram equals 0.001 kilograms.

How Many Grams Are in a Kilogram?

There are 1,000 grams in one kilogram.

Grams = (Amount of kilograms) x 1,000

How Many Kilograms Are in a Gram?

There are 0.001 kilograms in one gram.

Kilograms = (Amount of grams) ÷ 1,000

How to Convert Grams to Kilograms

To convert grams to kilograms, divide the number of grams by 1,000.

Convert grams to kilograms using this formula:

Kilograms = Grams divided by 1,000

Examples:

1 gram ÷ 1,000 = 0.001 kg

2 grams ÷ 1,000 = 0.002 kg

10 grams ÷ 1,000 = 0.01 kg

125 grams ÷ 1,000 = 0.125

250 grams ÷ 1,000 = 0.25 kg

500 grams ÷ 1,000 = 0.5 kg

1,000 grams ÷ 1,000 = 1 kg

You can also multiply the number of grams by 0.001.

Kilograms = Grams x 0.001

Examples:

10 grams x 0.001 = 0.01 kg

12.5 grams x 0.001 = 0.0125 kg

100 grams x 0.001 = 0.1 kg

500 grams x 0.001 = 0.5 kg

1,000 grams x 0.001 = 1 kg

Summary: To convert grams to kilograms, divide the number of grams by 1,000 or multiply the number of grams by 0.001.

How to Convert Grams to Kilograms by Shifting the Decimal Point

One easy way to convert grams to kilograms without doing any math is to shift the decimal point three spaces to the left. This conversion method works because the metric system is based on multiples of ten.

For example, to convert 77 grams to kilograms, you would move the decimal point to the right of the last 7 and fill in blank spaces with a zero. Seventy-seven grams can be written as 77.0 grams. Moving the decimal point three spaces to the left would result in 0.077 grams.

How to Convert Grams to Kilograms in Excel

To convert grams to kilograms in Excel, you need to use the CONVERT function, which converts a value in one system of measurement to another. For example, you can use the convert function to convert grams into pounds, gallons into liters, feet into meters, and more.

Syntax

When Was the Kilogram Redefined?

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.
