The Metric System

The metric system was designed as a way to standardize measurement and make conversions easier.

Before metrics units of measure many units were based off of body parts and so they commonly changed.

Standards were placed in city centers to compare to and often could be changed to short change peasants.

Based on Units of Ten

• Since Metrics are based on units of 10 all conversions are simply done by sliding a decimal point.

• All we need to determine the number of times the decimal point moves is to know how many units we have moved along the Metric Ladder.

A prefix is the beginning part of a word. In the Metric System it tells you how many of that unit you have.

Notice they are all divisible by 10!

Kilo means 1000 of a unit. Think large!

Kilometer (km) = 1000 meters

Kiloliter (kL) = 1000 liters

Kilogram (kg) = 1000 grams

Milli means 1/1000th of a unit. Think tiny!

Millimeter (mm) = 1/1000th of a meter

Milliliter (mL) = 1/1000th of a liter

Milligram (mg) = 1/1000th of a gram

Multiple Choice

If I wanted to measure how much water I will drink I would use.....

• Kiloliters

• centiliters

• milliliters

• liters

Multiple Choice

If I wanted to measure the weight of a bag of flour I would use....

• grams

• kilograms

• milligrams

• centigrams

Measuring distance

• Ruler

• Meter Stick

• Tape Measure

The Meter is the base unit used to measure length or distance. It is a little a more the height of a doorknob.

​

​Kilometer (1000 meters) is a large unit (over 1/2 a mile).

Centimeter (1/100th of a meter) is a small unit (about the width of your pinky).

​Millimeter (1/1000th of a meter) is very small (as thick as a dime).

Multiple Choice

If I wanted to measure the distance from my home to my work I would use.....

• Kilometers

• Meters

• Centimeters

• Millimeters

Multiple Choice

What tool do you NOT use to measure length?

• Ruler

• Graduated Cylinder

• Measuring Tape

• Meter Stick

Multiple Select

Which of the following measurements are SI units of length?

• Meters

• millimeters

• Feet

• Centimeters

Volume is the amount of space matter takes up. 

​

​The base unit is the Liter.

​

​Liters and milliliters are the most commonly used units.

Tools for Volume

If you want precise measurements use a Graduated Cylinder

​

A Beaker is a good tool when you don't have to have an exact amount.

Multiple Choice

This is a picture of

• a graduated cylinder

• a beaker

• a flask

• a test tube

Multiple Choice

To determine the volume of the liquid, you read the milliliter marking . .

• at the top of the meniscus

• two milliliters below the meniscus

• two milliliters above the meniscus

• at the bottom of the meniscus

Multiple Choice

The definition of Volume is:

• The distance between 2 points

• Amount of space a liquid takes up

• Amount of matter in an object

• A reading of a point in time

• Measure of the average energy of particles

Multiple Choice

What unit is used to measure volume?

• Meters

• Feet

• Milliliters

Mass is the amount of matter in an object.

​

​Scales and Balances are often used to measure mass. It is sometimes confused with weight which is different.

​

​The SI unit for mass is the kilogram (Kg).

The base unit for mass is the gram.

​Grams, kilograms, and milligrams are all commonly used.

Multiple Choice

A scale measures:

• Mass

• Time

• Temperature

• Volume

Multiple Choice

What unit is used to measure mass?

• Pounds

• Liters

• Centimeters

• Grams

Temperature

Measure of the average energy of particles. The faster the particles move, the "warmer" it is.

​

​The tool we use to measure is called a thermometer.

​

​The SI unit is the kelvin. In science we commonly use degrees Celsius as the unit.

Multiple Choice

Which measure of Temperature is used in the US?

• Celsius

• Fahrenheit

• Kelvin

Multiple Choice

Which Temperature Scale shows Absolute Zero?

• Kelvin

• Celsius

• Fahrenheit

Multiple Choice

Metric temperature is measured in:

• Fahrenheit

• Celcius

• Degrees

• Pounds

​Time

​The SI unit for time is the second (s).

​

​Time can be converted into minutes, hours, days, years, etc...

​

​It is not metric so it is not based on 10- except things smaller than a second. Example: Millisecond is 1/1000 of a second.
