metric system handout and 20 questions,

The Metric System , due Tuesday, Sept 22nd
The metric system is based on the number 10. There are, for example, 10 millimeters per centimeter. There are 1000 (10 times 10 times 10) meters per kilometer. (The prefix kilo- means one thousand times - so a kilometer is one thousand times the length of a meter.) There are one thousand milliliters in a liter. (The prefix milli- means “one thousandth of “ - so one milliliter would be one one-thousandth of a liter.)
In chemistry, physics - in fact, all the sciences, the metric system is used. The basic advantage to the metric system is that it is so easy to go from one unit to another. You just multiply or divide by 10.

Basic unit for measuring length is the meter. The symbol is m.
Basic unit for measuring volume is the liter. The symbol is v.
Basic unit for measuring mass is the gram. The symbol is g.

There are 1000 grams in a kilogram. 1,000g = 1 kg
There are 1000 meters in a kilometer. 1,000m = 1km
There are 1000 millimeters in a meter. 1,000mm = 1 m
There are 1000 milliliters in liter. 1,000ml = 1 l
Kilo- means 1000. The symbol is k. So the symbol for one kilogram is kg.
Milli- means 1/1000 or one one-thousandth. The symbol is m.
Centi- means 1/100th. The symbol is c. The symbol for centimeter is cm.
There are 10 millimeters in one centimeter. 10mm = 1 cm
1kg = 1000g 1/1000kg = 1g 1g = 100cg = 1000mg
