Examples:
```                 0.000 001 g
A 5 μg to g: 5 μg × —————   =   0.000 005 g
1 μg
0.000 000 001 m
B 42,000,000,000 nm to m: 42,000,000,000 nm × ————————      =   42 m
1 nm
1 μL
C 0.000 003 6 L to μL: 0.000 003 6 L ×  ————————      =   3.6 μL
0.000 001 L
```

Generally speaking, when you convert a number expressed using a smaller unit into a number expressed using a larger unit the number will get smaller (see examples A & B).

Also, when you convert a number expressed using a larger unit into a number expressed using a smaller unit the number will get bigger (see example C).

One last note: recognize the value of the prefixes when dealing with numbers like those in examples A & B. Who wants to write all those zeros when you can assume they are there just by knowing how small/large the prefix makes the base unit?

1. 5,679 g to kg
