The bridge method is the "recipe" for converting from one unit of measure to another. It can be used to convert ounces to pounds, quarts to pints, tablespoons to cups, grams to ounces, volume to weight, and so on.

Example: 12 teaspoons to cups

Step 1: If the unit of measurement that you are converting is a whole number, put it over 1. If it is a fraction, first convert it to a decimal and then put it over 1.

Step 2: Place a multiplication sign next to this.

Step 3: Draw another fraction line.

Step 4: Put in the units of measurement. The unit of measurement to be removed is written on the bottom. The unit of measurement to be converted to is written on top. The units diagonal to each other (that are the same) cancel each other out.
