The Metric System(Day 1)

SI (System International)9/15/10

Metric System

Used by every country in the world, except the USA.

Always used by scientists. Also called SI, which is French stands

for System International. Based on the number 10, so it’s

easy!

Measuring Length Length is the

distance between two points.

Basic unit = meter.

Meter = m We use rulers or

meter sticks to find the length of objects.

Measuring Mass

Mass is the amount of matter (stuff) that makes up an object.

Basic unit = gram.(g)

Measure using scales

Measuring Volume Volume is the

amount of space contained in an object.

Base unit = Liter (L).

We measure volume with a graduated cylinder or beaker.

Measuring Temperature

Temperature is the measure of the average heat or heat energy

Basic unit= degree Celcius (°C)

0°C= freezing, 100°C boiling

We use thermometers to measure temperature.

Let’s review our basic units!!!

Length Meter (m)

MassGram (g)

Volume Liter (L)

Temperature°C

We need more accuracy

We can’t measure everything with just basic units

We need prefixes!

Metric Prefixes Common prefixes from large to small:

kilo (k) - 1000centi (c )- 1/100th milli (m)- 1/1000th

We can add these prefixes before any of our basic units to make new units that are smaller or bigger!!!

Example: killogram (kg) = 1000 g 100 centimeters (cm) = 1 m

1000 milliliters (mL) = 1 L
