How Do You Convert Gallons to Teaspoons?
Multiply the number of gallons by 768 to get teaspoons. The formula is: Teaspoons = Gallons x 768. This works because a gallon has 16 cups, each cup has 16 tablespoons, and each tablespoon has 3 teaspoons: 16 x 16 x 3 = 768.
Coach Rivera calculates electrolyte powder servings from bulk containers. His 1-gallon jug of sports drink yields 768 teaspoons. Each serving calls for 2 teaspoons mixed into 8 ounces of water, so one gallon of concentrate provides 384 servings for his athletes.

Practical Applications
Medicine and Supplements
Tom Whitfield buys liquid fish oil in a gallon jug for cost savings. The daily dose is 1 teaspoon, so one gallon lasts 768 days, or about 2 years and 38 days. He writes the start date on the bottle and calculates the expiration date to make sure the product will still be good.
Cooking with Extracts
Leah Novak purchases vanilla extract in gallon jugs for her bakery. Each batch of cookies needs 2 teaspoons. One gallon gives her 768 / 2 = 384 batches of cookies. At 4 batches per day, a gallon lasts about 96 working days, or roughly 4 months.
Water Treatment
Sam Okafor treats well water with iodine drops measured in teaspoons. The treatment calls for 0.5 teaspoons per gallon of water. For a 50-gallon holding tank, he needs 25 teaspoons of iodine solution. His gallon bottle of treatment fluid holds 768 teaspoons, enough for 768 / 0.5 = 1,536 gallons of treated water.
