### Metric System

I will be ale to measure to record data using a variety of SI units.

Tuesday, March 11, 2014

• The first standardized system of measurement, based on the decimal was proposed in France about 1670.

• It was created to develop a unified, natural, universal system of measurement.

• In 1790 King Louis XVI of France assigned a group to begin this task.

• At that time, every country had their own system of weights and measures. England had three different systems just within its own borders!!

• It was called the "metric" system, based on the French word for measure.

• 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.

• Meter

• Length

• Liter

• Volume

• Gram

• Weight or Mass

• 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.

• 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

• One side has inches (duh!)

• 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

How to remember different volumes in the metric system: measure the items on your chart.

• 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: measure the items on your chart.

• 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.

1 m = 100 cm measure the items on your chart.

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

Measurement Conversions to Know:

• 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? measure the items on your chart.

• King Henry Died by Drinking Chocolate Milk

• King: Kilo

• Henry: Hecto

• Died: Deca

• By: Base (m, L, g)
