*If you move from left to right (going to smaller units), you will multiply by 10 each time
*If you move from right to left (going to bigger units), you will divide by 10 each time

5. 1. Write what you know over 1
CONVERSIONS:
1. Write what you know over 1
Find conversion factor– write it in correct order
Cancel out units
Repeat as necessary
Multiply/ divide
Ex. How many seconds are in 1 year?
1 year X 365 days X 24 hours X 60 min. X 60 sec. = 31,536,000 sec.
year day hour min.
