1.55 x 106 nm =
km
This is just a metric conversion ---- always 2 steps.
Start with what
you’re given:
One step to the
BASE unit, meters:
One step to the desired
unit, kilometers:
1.55 x 106 nm x 1x10-9m x
1 nm
1 km
1x103 m
1.55x10-6 km

8.5 x 10-20 Ml =
ml
This is just a metric conversion ---- always 2 steps.
Start with what
you’re given:
One step to the
BASE unit, liters:
8.5 x10-20 Ml x 1x106 l
1 Ml
One step to the desired
unit, milliliters:
x
Or you could use this for last fraction 
1 ml
1x10-3 l
1000 ml
1 l
8.5x10-11 ml
8 gallons =
liters
Gallons is an English unit and liters is a metric unit - determine what
Metric-English conversion will work (from box at top of homework)
