About converting Fluid Ounces (US) to Teaspoons
Fluid Ounces (US) (fl oz) and Teaspoons (tsp) are both units of volume, so converting between them is a single multiplication: multiply your Fluid Ounces (US) figure by 6. Ten Fluid Ounces (US) comes to 60 Teaspoons, and a hundred works out at 600 Teaspoons.
Rule of thumb: going from Fluid Ounces (US) to Teaspoons multiplies, so the figure always grows — one Fluid Ounce (US) is already 6 Teaspoons. If your answer came out smaller, you have the conversion the wrong way round.
What is a Fluid Ounce (US)?
A fluid ounce measures volume, not weight, despite sharing a name with the ounce on a kitchen scale — the two are related only loosely, through the weight of water. The US and imperial fluid ounces are different sizes, and counterintuitively the imperial one is the smaller, even though the imperial gallon is the bigger of the two: the imperial gallon divides into 160 fluid ounces, the US gallon into just 128. The gap is small enough to slip past a reader and large enough to matter, which makes it a reliable trap in cocktail recipes and drink can sizes.
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.
To put both in perspective: a US shot of spirits is about one and a half fluid ounces, while a teaspoon is the standard measure for baking powder in a recipe.
