CONVERTING UNITS

to convert from smaller units to larger units → divide

to convert from larger units to smaller units → multiply

2 kilometers = 2 kilometers \times \frac{1,000 meters}{1 kilometer} = 2,000 meters

3 feet = 3 feet \times \frac{12 inches}{1 foot} = 36 inches

Now, convert 36 fluid ounces to cups.
There are 8 fluid ounces in 1 cup.
To convert fluid ounces to cups, divide the number of fluid ounces by 8.

36 fl oz = 36 fl oz \times \frac{1 c}{8 fl oz} = 4.5 c
