Introduction to the Metric SystemIT IS SOOOOOOO MUCH EASIER THAN YOU REALIZE!!!!
Different ways to measure…
What are some of the ways we measure?
(3 most common…)
Distance
Measurement how far it is from one location to another.
Volume
How much space something takes up.
Mass
Amount of matter in an object.
In the US we use… Standard system of measurement…
Distance
Point
Pica (1 Pica = 12 Points)
Inch (1 Inch = 6 Picas = 72 Points)
Foot (1 Foot = 12 Inches = 72 Picas = 864 Points)
Yard (1 Yard = 3 Feet = 36 Inches = 216 Picas = 2592 Points)
Mile
= 1760 Yards
= 5280 Feet
= 63,360 Inches
= 380,160 Picas
= 4,561,920 Points

History of Metric System
History
Called Systeme International d’Unitès, or SI - International System of Units
Revised periodically by International Bureau of Weight and Measures
Advantages of Using the Metric System
Simple to use A few base units make up all
measurementslength - meter mass - grams volume - liters temperature – degrees Celsius
Advantages of Using the Metric System
There is only one unit of measurement for each type of quantity To simplify things, very small and very large
numbers are expressed as multiples of the base unit.
Prefixes are used to represent how much smaller or larger the quantity is compared to the base unit.
Easy to convert from one unit to another shift decimal point right shift decimal point left
Advantages of Using the Metric System Same set of prefixes for all units
Greek - multiples of the base kilo - 1000 × the basehecto - 100 × the base deka - 10 × the base
Latin - fractions of the base deci - tenths of the base centi - hundredths of the base milli - thousandths of the base
Metric Prefixes
Mnemonics… Kilo = 1000 (one thousand)
Hecto = 100 (one hundred)
Deka = 10 (ten)
Base = 1 (One)
Deci = .1 or 1/10 (one tenth)
Centi = .01 or 1/100 (one hundredth)
Milli = .001 or 1/1000 (one thousandth)
