The Metric System (Day 1) SI (System International) 9/15/10
Metric System Used by every country in the world, except the USA. n Always used by scientists. n Also called SI, which is French stands for System International. n Based on the number 10, so it’s easy! n
Measuring Length n n 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 is the amount of matter (stuff) that makes up an object. n Basic unit = gram. (g) n Measure using scales n
Measuring Volume n n n 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 is the measure of the average heat or heat energy n Basic unit= degree Celcius (°C) n 0°C= freezing, 100°C boiling n We use thermometers to measure temperature. n
Let’s review our basic units!!! n n Length ¨ Meter (m) Mass ¨ Gram (g) Volume ¨ Liter (L) Temperature ¨ °C n n n We need more accuracy We can’t measure everything with just basic units We need prefixes!
Metric Prefixes n Common prefixes from large to small: kilo (k) - 1000 centi (c )- 1/100 th milli (m)- 1/1000 th 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 (m. L) = 1 L
