Step-by-step explanation:

Use the cross product cancellation method.

Place the value you are converting in the upper left corner. Then diagonally place the same unit and above it what it is equal to in one larger or one smaller units. Continue this until you have reached the unit you need. Multiply every value on the top together. And every value on the bottom together. Divide the top value by the bottom value.
