1. Metrics

2. I know you learned it before…
K h da O d c m
Kids have dropped over dead converting metrics. OR

3. Metrics
K h da m d c m
Kangaroos hop down mountains drinking chocolate milk.

4. Metrics
K h da O d c m
Here is how it works:

5. Metrics
The letters represent:
kilo,
hecto,
deca,
( base unit),
deci
centi
milli

6. Metrics
K h da d c m
The base unit (gram, meter, liter, etc.) goes in the circle.
You know it is a base unit when it is only one letter: m, g, l

7. Metrics
K h da g d c m
Convert: g to kg
376.9 g = kg

8. Let’s Try again!
K h da g d c m
Convert: hl to ml
hl = 158 ml

9. One more
K h da g d c m
Convert: mg to dag
17.9 mg = dag

10. You Try!
Convert:
km to m
mm to hm
65.40 mg to cg
3200 L to kL
kg to mg
1.75 g to cg

11. Answers
Convert:
km = 8.00 m
mm = 0.25 hm
65.40 mg = cg
3200 L = 3.2 kL
kg = mg
1.75 g = 175 cg

12. Two others
Mega and Micro are two more metric prefixes we will use in chemistry.
Mega = M = 1 million
Micro =  = 1 millionth

13. Two others
M _ _ K h da g d c m _ _ 
Convert Mm to hm
Convert g to dg

14. You Try!
Convert:
mg to g
Mm to cm
g to cg
3200 mL to hL
g to mg
6500 g to kg

15. Answers
Convert:
mg = g
Mm = 67.8 cm
g = 65.4 cg
3200 mL = hL
g = 60.8 mg
6500 g = 6.5 kg

16. Other prefixes
Giga (G) = Mega  1000
Terra (T) = Giga  1000
Nano (n) = Micro x 1000
Pico (p) = Nano x 1000
