7. You are probably also familiar with some of the metric system units
You are probably also familiar with some of the metric system units.  Match these...
A  2 ______ bottle of soda.
A  ________ of sugar.
A  ________ stick.
a.  gram b.  liter c.  meter

8. English Units Length Area
12 inches = 1 foot square inches = 1 square foot
3 feet = 1 yard 9 square feet = 1 square yard
220 yards = 1 furlong 4,840 square yards = 1 acre
8 furlongs = 1 mile acres = 1 square mile
5,280 feet = 1 mile 1 square mile = 1 section
1,760 yards = 1 mile 36 sections = 1 township
Volume Capacity (Dry)
1,728 cubic in. = 1 cubic foot grains = 1 ounce
27 cubic feet = 1 cubic yard bushel = 8 dry gallons
8 dry quarts = 1 peck
Mass Capacity (Liquid)
14 pounds = 1 stone 16 fluid ounces = 1 pint
100 pounds = 1 hundredweight 4 gills = 1 pint
2 pints = 1 quart
4 quarts = 1 gallon

9. Metric Prefixes
Base Units
Length =meter
Mass = gram
Volume = liter

10. SI (System of International) Units
Uses powers of 10 (10-1, 101, 102, 103,etc.)
Uniform way to present and report data across the world.
How is SI different than our American units?
Why do scientists use this system?

11. Basic Units
Meter (m)
length
Gram (g)
mass
Liter (l)
volume

12. Prefixes Add to the beginning of a Basic Unit Nano (n) Micro ()
Milli (m)
Centi (c)
Deci (d)
Deca (da)
Hecto (h)
Kilo (k)
Example: cm = centimeter
Example: mg = milligram

13. Metric System
If you needed to measure length you would choose meter as your base unit
Examples:
-Length of a tree branch
1.5 meters
-Length of a room
5 meters
-Length of a ball of twine stretched out
25 meters

14. Length Measurements Millimeter = small objects, like a quarter
Centimeter = small objects, your foot or even your height
Meter = larger distances, the size of a room
Kilometer = much larger distances, Vancouver to Seattle

15. Metric system units are base 10, so it is easy to convert
Ex.   There are 10 millimeters in 1 centimeter
         100 centimeters in 1 meter
A mm is about as thick as a dime.   Notice there are about 10 dimes between the 6 and the 7 on this photo.
The large number represent centimeters.

16. Don't worry about converting inches to centimeters - just measure in centimeters to start with; hence, METRIC ruler
Use your metric ruler to calculate ..
1. Width of your desk  _______ cm
2. Width of your desk  ______ mm
3. Length of your index finger _____ cm
4. Length of your index finger ______mm

17. Volume measures the amount of space something takes up, usually a liquid.
SI units for volume:
-Liter
-Milliliter
Beakers and Graduated cylinders used to measure volume

18. How to read a graduated cylinder
The smallest quantity that can be measured accurately using a measuring instrument.
Indicates the degree of accuracy of measurement that can be achieved by the measuring instrument.
Always estimate past the last count.

19. CC = cubic centimeter, which is the same as a ml
Used in medicine

20. Mass: the amount of matter in an object
      Measured in grams and kilograms
           Weight measures mass + gravity
