The Metric System (Day 3)(Kilo… to milli… units)
We are learning to…convert metric units of length, mass, and volume.
Thursday, April 20, 2023
What is the Metric System? System of measurements that is based on
increments of 10. Why should I learn about the Metric System
of Measurement? Much easier to convert measurements compared
to the English System of Measurement Over 95% of the world uses the metric system.
In fact only 3 countries still use the English System of Measurement Myanmar Liberia The United States
The basic units of the Metric System:
A METER is the basic unit of length in the Metric System.
A GRAM is the basic unit of weight and mass in the Metric System Think of the weight of a gram to be
about 1 paper clip. A LITER is the basic unit of volume in
the Metric System.
There are also units of the Metric System which are smaller than the basic units.

Moving from a larger unit to a smaller unit you must multiply because there are a lot of the smaller units inside of the larger unit.
÷10÷10 ÷10÷10÷10÷10
Moving from a smaller unit to a larger unit you must divide because you must see how many groups of the smaller units are inside the larger unit.
Converting Between Metric Units…
17 m = ________ cm
Larger unit to a small unit… so multiply
17 m × 10 × 10
1,700 86,000 mg = ________ g
Smaller unit to a larger unit… so divide
86,000 mg ÷ 10 ÷ 10 ÷ 10
86
9.81 dl = ________ cl
Larger unit to a small unit… so multiply
9.81 dl × 10
98.1 83 mm = ________ m
Smaller unit to a larger unit… so divide
83 mm ÷ 10 ÷ 10 ÷ 10
0.083
•Try converting some metric units of length, weight/mass and volume with your teammates. Raise your hand when you are complete so your teacher can check your solutions.
Units which are larger than the basic units… There are also units which are larger than the basic
units:
10 of the basic unit put together are called a decameter, decagram, or decaliter.
To remember this think of a decade. A decade is 10 years, while a “decaunit” has 10 units put together.
100 of the basic unit put together are called a hectometer, hectogram, or a hectoliter.
1,000 of the basic unit put together are called a kilometer, kilogram, or a kiloliter.
