How many teaspoons are in a 16 oz of baking soda?

First you need to know that 1 tsp = 0.1667 oz So, if you take the number of ounces in the box of baking soda (found at the bottom of the box) and divide it by 0.1667 you'll get the number of teaspoons in that box! Therefore, in an 8 oz box of baking soda there are 48 tsp, and in a 1 lb box (which is 16 oz) there are 96 tsp, etc. I hope that helps!
