The Metric System The Metric System is a system of measurement based on the number 10. These measurements include: Length: the distance between two points. Volume: the amount of space an object takes up. Mass: the amount of matter in an object. Temperature: the measure of hotness or coldness.

What are the main units for these measurements? Length: Meter (m) Volume: Liter (L) or cubic meter (m3) Mass: Gram (g) Temperature: degree Celsius (0C) Time: seconds (s)

Basic Comparsions A tall tree is roughly 40 m An average 12 year old is 1.5 m A meter stick is 1 m. Width of your pink is .01 m Thickness of paper is less than .001 m How many meters long is a paperclip?

What was the problem? The paperclip was too small to measure with a meter stick. No Worries! The metric system can be multipled or divided by multiples of 10 to measure objects that are bigger or smaller!

What are these multiples called? Giga- G Mega- M Kilo- K Hecto- H Deka- D (Base Unit) m,L,g Deci- d Centi- c Milli- m Micro- μ Nano n
