Gallon to Teaspoon (gal to tsp) Converter
1 US gallon equals 768 teaspoons (tsp) — multiply the number of gallons by 768 to convert. A teaspoon is the smallest common kitchen measure, so a single gallon holds a surprisingly large number of them, and the factor stays fixed for every value.
The formula
To convert gallons to teaspoons, multiply by 768:
tsp = gallons × 768
For example, 2 gallons × 768 = 1,536 teaspoons. To reverse it, divide teaspoons by 768 (or multiply by 0.00130208).
