About converting Teaspoons to Fluid Ounces (US)
Teaspoons (tsp) and Fluid Ounces (US) (fl oz) are both units of volume, so converting between them is a single multiplication: multiply your Teaspoons figure by 0.1667. Ten Teaspoons comes to 1.6667 Fluid Ounces (US), and a hundred works out at 16.6667 Fluid Ounces (US).
Rule of thumb: going from Teaspoons to Fluid Ounces (US) divides, so the figure always shrinks — it takes about 6 Teaspoons to make a single Fluid Ounce (US). 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 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.
To put both in perspective: a teaspoon is the standard measure for baking powder in a recipe, while a US shot of spirits is about one and a half fluid ounces.
