First start with what you are given. Figure out what units you need. You will need to create a ratio (conversion factor) between the units given and the units needed. Ask yourself which unit is bigger. Put a "1" by that unit. Then ask how many of the smaller units are in the bigger unit. Put that number in front of the smaller unit.
