If you are cooking, you need to know how to change teaspoons to tablespoons and tablespoons to ounces. These measurements are also important if you are using concentrated cleaning or hair care supplies and must dilute them. The conversions are simple, yet they can cause disastrous results if measured incorrectly.
Use standard cook's measuring spoons. Do not use teaspoons and soup spoons from your flatware set. They may vary in size.
Measure 3 tsp. for 1 tbsp. Teaspoon is often abbreviated to t. or tsp., and tablespoon may be abbreviated T. or tbsp. Other short forms may be used as well.
Measure 1 1/2 tsp. for 1/2 tbsp. Some sets of measuring spoons include a 1/2 tbsp. size, but many do not.
Measure 2 tbsp. for 1 oz. If you do not have a tablespoon measuring spoon, measure 6 tsp. instead to equal 1 oz. These are standard measurements for cooking and for diluting common cleaners. You can use a standard liquid measuring cup for ounces as well.
