About converting Teaspoons to US Gallons
Teaspoons (tsp) and US Gallons (gal (US)) are both units of volume, so converting between them is a single multiplication: multiply your Teaspoons figure by 0.001302. Ten Teaspoons comes to 0.01302 US Gallons, and a hundred works out at 0.1302 US Gallons.
Rule of thumb: going from Teaspoons to US Gallons divides, so the figure always shrinks — it takes about 768 Teaspoons to make a single US Gallon. If your answer came out bigger, you have the conversion the wrong way round.
What is a Teaspoon?
The teaspoon is the smallest unit most kitchens ever measure, and it is the base the spoon system is built on — a tablespoon is defined as three of them. It is precise enough for baking powder, salt and vanilla, where the gap between a level spoon and a heaped one decides whether a cake rises. What it should not be used for is medicine: health authorities discourage dosing by teaspoon precisely because the spoons people actually reach for vary widely in size, and recommend a marked oral syringe or dosing cup in milliliters instead.
What is an US Gallon?
The US gallon is defined as exactly 231 cubic inches, a figure inherited unchanged from the old English wine gallon. When Britain overhauled its measures in 1824 and adopted a new imperial gallon, the United States simply kept the wine gallon it already had — and that single decision is the root of the entire US-versus-imperial mess that still catches people out today. The US gallon is roughly a fifth smaller than the imperial one, which means American and British fuel-economy figures are not comparable even though both are quoted in miles per gallon.
To put both in perspective: a teaspoon is the standard measure for baking powder in a recipe, while a typical American milk jug holds one US gallon.
