Cups to Teaspoons Converter

What is a cups to teaspoons converter?

A cups to teaspoons converter turns a volume given in US cups into the equivalent number of US teaspoons. It is handy when a recipe lists an ingredient in cups but you only have measuring spoons on hand, or when you need to scale a small batch down to spoon-sized portions. Enter any value and the tool returns the matching teaspoon count immediately, working in both directions.

Formula

One US cup holds 236.588 mL and one US teaspoon holds 4.92892 mL, so the conversion is a fixed ratio:

$\text{Teaspoons} = \text{Cups} \times \frac{236.588}{4.92892} = \text{Cups} \times 48$

To go the other way, divide the number of teaspoons by 48:

$\text{Cups} = \frac{\text{Teaspoons}}{48}$

How to convert cups to teaspoons

1. Take the amount measured in US cups.
2. Multiply it by the base factor: 1 US cup = 48 US teaspoons.
3. The result is the equivalent volume expressed in US teaspoons.

Because the factor is a clean 48, mental math is easy: half a cup is 24 teaspoons, a quarter cup is 12 teaspoons.

Worked examples

Example 1: 1 cup to teaspoons

$1 \times 48 = 48 \text{ teaspoons}$

So 1 US cup equals 48 US teaspoons.

Example 2: 96 teaspoons to cups

$\frac{96}{48} = 2 \text{ cups}$

So 96 US teaspoons equal 2 US cups.
