Lesson Transcript
Instructor: Sarah Kaiser

Sarah has taught 3rd and 5th grade and has a master's degree in education.

In this lesson, we'll explore how to use the units of measurement called grams and kilograms, which describe mass. We'll learn about the two separately and then explore how the two units stack up to each other.

Grams and Kilograms

Imagine being at the beach and running you fingers through the sand. Have you ever tried to pick up a grain or even a handful of sand? It's pretty light! Now, think about a large rock sitting on the beach. Would you be able to lift this on your own? Probably not. It's much heavier than sand. We could measure that heavy rock in kilograms and that much lighter handful of sand in grams.

While the United States and a few other locations measure weight in pounds and ounces, most of the world uses the metric system. Grams and kilograms are used to measure mass in the metric system. Let's learn more about these two units of measurement.


Grams is a unit of measurement used to measure very light objects. For example, a small metal paperclip has a mass of around 1 gram. Other objects with a mass of about 1 gram are a stick of gum and a dollar bill. We can abbreviate the unit gram with the letter g.


Kilogram is a unit of measurement used to measure much heavier objects. For example, a one-liter bottle of soda has a mass of about 1 kilogram. Fruits such as small watermelons and pineapples also have a mass of around 1 kilogram. We can abbreviate the unit kilogram with the letters kg.
