Convert teaspoons ⇄ cups

1 cups
48 tsp = 1 cups (US cups & teaspoons)

Formula: 48 tsp ÷ 48 = 1 cups

How the teaspoons to cups conversion works

The ratio is exact: cups = tsp ÷ 48. It chains two exact kitchen ratios: 1 US cup = 16 US tablespoons, and 1 US tablespoon = 3 US teaspoons — so 1 cup = 16 × 3 = 48 teaspoons. Going the other way, tsp = cups × 48.

Worked example: a spice mix calling for 36 tsp of cumin needs 36 ÷ 48 = 0.75 cups (¾ cup). And half a cup of sugar is 0.5 × 48 = 24 teaspoons.

Small spoon measurements multiply fast, which is where rounding sneaks in. If a scaled-up recipe gives you 41 tsp, the exact figure is 41 ÷ 48 ≈ 0.854 cups — measure it as about ⅚ of a cup, or keep the teaspoons. For amounts under 3 tsp, tablespoons are the cleaner unit: try our tablespoons to teaspoons converter.

teaspoons to cups questions

How many teaspoons are in a cup?
48 US teaspoons in 1 US cup. It follows from the two exact kitchen ratios: 1 cup = 16 tablespoons, and 1 tablespoon = 3 teaspoons, so 16 × 3 = 48 tsp per cup.
How do I convert teaspoons to cups?
Divide by 48: cups = tsp ÷ 48. So 24 tsp is 24 ÷ 48 = 0.5 cups, and 96 tsp is 2 cups. Type any figure above to get the exact decimal.
How many cups is 12 teaspoons?
0.25 cups — a quarter of a cup (12 ÷ 48). Handy equivalents: 16 tsp = ⅓ cup, 32 tsp = ⅔ cup, 48 tsp = 1 cup.
Is this the US teaspoon?
Yes — the US teaspoon (4.92892 ml). The metric teaspoon (5 ml, used in the UK and Australia) differs by about 1.4%, which barely matters in cooking but is worth knowing when a recipe from another country uses "tsp".
How do I convert cups back to teaspoons?
Multiply by 48: tsp = cups × 48. So ¾ of a cup is 0.75 × 48 = 36 teaspoons. Switch the direction above to do it.
