Zuri and Freddie are scientists for the day. They have their white coats on and are ready to collect data on some marine species. They need our help calculating how much several of them weigh. In order to do that we need to know what are units of mass and how to convert units of mass.

### What is Mass?

When we measure **mass**, we are measuring the amount of matter that makes up an object. What are units of mass? Mass must be measured in units of grams and kilograms.

#### How Much is a Gram?

A gram is one of the units of measurement for mass. We use grams to measure smaller objects, like a small seashell. One small seashell weighs about one gram. When we write grams, we can abbreviate using the letter ‘g’.

#### How Much is a Kilogram?

A kilogram is also one of the units of measure for mass. We use kilograms to measure larger objects, such as a pineapple. One pineapple weighs about one kilogram. When we write kilograms, we can abbreviate using the letters ‘kg’.

Now that we know a little more about the units used to measure mass of an object, let’s learn about converting kilograms to grams and converting grams to kilograms.

#### Converting Units of Mass

Since we know what units of measurement are used for mass, let’s see how we can convert them using a units of mass chart, also known as a ratio table. One kilogram is equal to one thousand grams and one thousand grams is equal to one kilogram.

The table below shows metric units of mass, and how to convert three kilogram into grams. Since one kilogram is equal to one thousand grams, we multiply three kilograms by one thousand to get three thousand grams.

If we want to convert fourteen thousand grams into kilograms, we solve it by using the inverse, or opposite, operation. Fourteen thousand grams divided by one thousand is fourteen kilograms.

#### Mass Units of Measurement and Conversion Summary

What are the units of mass? Mass must be measured in units of weight, such as grams and kilograms. We can convert them using a units of mass chart, also known as a ratio table. We can use a ratio table to convert kilograms to grams and grams to kilograms.

**How to Measure Grams and Kilograms**

Zuri and Freddie are scientists for the day. They have their white coats on and are ready to collect data on some marine species. They need our help calculating how much several of them weigh. Before we start, we need to know "how to measure grams and kilograms". "Matter is anything that has weight or mass and takes up space". When we measure "mass, we are measuring the amount of matter that makes up an object". We measure mass in units called GRAMS and KILOGRAMS. A gram is "a unit used to measure mass". We use grams to measure smaller objects, like a small seashell. When we write grams, we can abbreviate using the letter
