What is the metric system?

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.

About the size of a bottle of water.

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
