How to Convert Gallons to Tablespoons

To convert a measurement in gallons to a measurement in tablespoons, multiply the volume by the following conversion ratio: 256 tablespoons/gallon.

Since one gallon is equal to 256 tablespoons, you can use this simple formula to convert:

tablespoons = gallons × 256

The volume in tablespoons is equal to the volume in gallons multiplied by 256.

For example, here's how to convert 5 gallons to tablespoons using the formula above.

tablespoons = (5 gal × 256) = 1,280 tbsp
