About this tool
Convert US gallons to teaspoons instantly. Free, bidirectional, and fully in-browser.
1 us gallon equals 768 teaspoons — enter any us gallon value to convert it to teaspoons instantly. This US gallon to Teaspoon converter is a client-side tool: it applies a single multiplication (tsp = gal × 768) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert teaspoons back to US gallons. A reference table lists common us gallon values already converted, and nothing you enter is sent to a server.
Open US gallon to Teaspoon Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the US gallon field.
Read the equivalent in teaspoons in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert teaspoons to US gallons.
The result updates as you type, and the swap button flips the conversion to teaspoon → us gallon without reloading.
The conversion uses the precise factor (tsp = gal × 768), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
One us gallon is 768 teaspoons. Multiply the us gallon value by 768 to convert. For example, 10 gal = 7680 tsp.

Yes. Press the swap button, or type into the teaspoon field, and the tool converts teaspoons to US gallons using the inverse of the same relationship.
It uses the standard volume and capacity definition (tsp = gal × 768), not a rounded approximation, so results are exact to the number of decimal places you select.
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
