Metric System

What is the metric system?
The first standardized system of measurement, based on the decimal called the "metric" system. As of 2005, only three countries, the United States, Liberia, and Myanmar, have not changed over to the metric system. The official modern name of the metric system is the International System of Units or abbreviated SI.

Why use it? Almost all other countries are using the metric system
Other countries’ companies are refusing to buy products from the U.S. if not labeled in metric units Scientists need a universal way to communicate data (SI Units)

What are the metric measurements that we are learning about?
Meter Length Liter Volume Gram Mass

How to remember different lengths in the metric system:
When you think of a millimeter (mm) think of: The thickness of a dime. When you think of a centimeter (cm) think of: The width of your pinky.

How to remember different lengths in the metric system:
When you think of a meter (m) think of: The height of the doorknob. When you think of a kilometer (km) think of: A little more than half of a mile

How to understand the ruler:
One side has inches The other side is the metric side. The big numbers represent centimeters The smaller lines represent millimeters. How many millimeters are in a centimeter? 10

With the group you will be put into, use a meter stick to measure the items on your chart.
Be sure to measure in meters, centimeters, and millimeters.

How to remember different volumes in the metric system:
When you think of a liter (L) think of: About the size of a bottle of water. When you think of 5 milliliters (mL) think of: One teaspoon When you think of 2 kiloliters (kL) think of: A hot tub

How to remember different masses in the metric system:
When you think of a gram (g) think of: A paper clip When you think of a kilogram (kg) think of: A little more than 2 pounds.

Measurement Conversions to Know:
1 m = 100 cm 1 cm = 10 mm 1 m = 1,000 mm 1 km = 1,000 m 1 g = 100 cg 1 cg = 10 mg 1 g = 1,000 mg 1 kg = 1,000 g 1 L = 100 cL 1 cL = 10 mL 1 L = 1,000 mL 1 kL = 1,000 mL

What is the order of the metric system?
King Henry Died by Drinking Chocolate Milk King: Kilo Henry: Hecto Died: Deca By: Base (m, L, g) Drinking: Deci Chocolate: Centi Milk: Milli
