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)
