The Metric System

A simple way to measure

What is it???

A system of measurement based on multiples of 10

010.010.1

000.001

Each Multiple has its own name

Milli = 0.001 or 1/1000

Deca = 10

Centi = 0.01 or 1/100

Deci = 0.1 or 1/10

= 1 (no prefix)

Each Multiple has its own name

Hecto = 100

Kilo = 1000

Length – “the Meter”How long is something? We use the Meter to measure

the length of objects

A meter is almost equal to a yard in the English System

* 1 yard= .9144 meter, 1 m = 3.28 feet, 1 yard = 3 feet

The Meter Comes in Different Sizes

Millimeter Centimeter Meter Kilometer

1 inch = 25.4 mm 1 mile = 1.6 km 1 m = 3.28 ft 1 inch = 2.54 cm

1 Centimeter

10 Millimeters

1mm1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm 1mm

Is the same as

1 Meter

100 CentimetersIs the same as

100 Centimeters

1000 Millimeters

Which is the same as

1 MeterIs the same as

1 Kilometer

1000 MetersIs the same as

Need to Know!!!!

10 mm = 1 cm 100 cm = 1 m 1000 m = 1 km

1000 mm = 100 cm 1000 mm = 1 m

How many mm = 1 km ???

The “Need to Know” on the previous slide holds true for EVERY unit of measurement in the metric system! You can substitute in gram for meter, or liter for gram… all three have the same exact conversions!

Keep this in mind as you continue through the presentation!

Mass – “the Gram”

Mass is a measure like weight, or how heavy something is.

Measurement like ounces and pounds. The gram is closest to an ounce in the

English System of measurement(1 ounce weighs about the same as a slice of bread,

1 gram = about one paperclip!)

The gram comes in different sizes too!

Milligram gram kilogram

1 oz = 28.35 grams 1 pound = 2.2 kg

Volume – “the Liter”

Volume tells how much space an object takes up

Used to measure liquids Measurement like cups, ounces and

gallons The liter is closest to a quart in the

English System of measurement(1 liter = 1.056 quarts, 1 quart = 4 cups)

The Liter comes in different sizes like the meter and gram!

Milliliter Liter Kiloliter

1 gallon = 3.78 liters5 ml = 1 teaspoon = 1 cc
