2. Example 1 Convert: a) 5,000 mm = ____ m b) 1.7 kg = ____ g
c) ____ ml = 6 cl
Key points:
If there is no decimal point, put one in.
When moving the decimal point, add a zero if there is no number where you are moving to.

3. Conversion Factors 1 jerk = 13 snaps 1 snap = 6.6 crackles
1 crackle = 1000 pops

4. Example 2 Convert: a) 50 jerks to snaps (1 step)
b) 9000 pops to snaps (2 steps)
c) 250 crackles to jerks (2 steps)

5. Length Conversion Factors
1 inch = 2.54 cm
1 ft. = 12 in.
1 mile = 1600 m
1 mile = 5280 ft.
1 yard = 3 ft.

6. Time Conversion Factors
1 min = 60 sec
1 hr = 60 min
1 day = 24 hr.
1 year = 365 days

7. Example 3 Convert: a) 3 feet to centimeters (2 step)
b) 1 day to seconds (3 steps)

10. Scientific Notation
The internationally recognized way of communicating values in science
Exponent tells number of zeros

11. Follow same rules as Metric Conversion
If there is no decimal point, put one in.
When moving the decimal point, add a zero if there is no number where you are moving to.

12. Examples How many and in what direction:
Remember:
If there is no decimal point, put one in.
When moving the decimal point, add a zero if there is no number where you are moving to.
How many and in what direction:
Write without scientific notation:
= __________
= _________ 12

13. Now, do it backwards To write a number in scientific notation
Place a decimal if there isn’t one already
Move the decimal to the left or right until there is only one number in front of (or to the left of) the decimal place
Count the number of times you moved
Write that number as the exponent of the 10
If you moved right, make exponent negative
If you moved left, make it positive
NOTE: It’s the reverse of writing without scientific notation 13

14. Examples How many and in what direction: 3,600 0.0058
Write the Following in scientific notation:
65,000 = ____________
0.015 = _____________
25 = _______________ 14
