Gallon to Tablespoon (gal to tbsp) Converter
1 US gallon equals 256 tablespoons (tbsp) — multiply the number of gallons by 256 to convert. Because a gallon is a large volume and a tablespoon is small, the numbers grow quickly, but the factor never changes, so every gallon-to-tablespoon conversion is exact.
The formula
To convert gallons to tablespoons, multiply by 256:
tbsp = gallons × 256
For example, 3 gallons × 256 = 768 tablespoons. To go the other way, divide tablespoons by 256 (or multiply by 0.00390625).
