To find the length of a computer keyboard, we can use a ruler. On a ruler, the metric units are usually centimeters, often abbreviated as (cm).
We will review what we know about metric units of length. Let's start by taking a look at the table below which shows different units.
Metric Units of Length |
---|
1 kilometer = 1000 meters |
1 meter = 100 centimeters |
1 centimeter = 10 millimeters |
Note that when we need to convert from smaller to larger units, we multiply. When we want to convert from larger to smaller units, we divide. Now let's assume that we measured our keyboard and found that it is 40 centimeters long.
