There are 48 teaspoons in 1 US cup. This is because 1 US cup equals 16 tablespoons, and each tablespoon equals 3 teaspoons (16 × 3 = 48). For Imperial cups, 1 cup equals approximately 57.6 Imperial teaspoons.
Multiply the number of cups by 48 to get US teaspoons: teaspoons = cups × 48. For example, 2 cups = 2 × 48 = 96 teaspoons. For Imperial measurements, multiply cups by 57.6 instead.
A cup is a unit of volume used in cooking and baking. The US customary cup equals 236.6 ml (about 240 ml for the US legal cup), while the Imperial cup is approximately 284 ml. Standardized measuring cups are used in recipes rather than regular drinking cups, which vary widely in size.
A teaspoon (abbreviated tsp) is a small unit of volume used primarily in cooking. The US teaspoon equals approximately 4.93 ml, while the Imperial teaspoon is about 5.92 ml. Three teaspoons make one tablespoon.
A US customary cup equals approximately 236.6 ml, and the US legal cup (used in nutrition labeling) is exactly 240 ml. An Imperial cup is larger at about 284 ml. The difference matters in baking — US recipes and Imperial recipes will yield different amounts when using the same number of cups.
Simply multiply the fractional value by 48. For example, ¼ cup = 0.25 × 48 = 12 teaspoons, ½ cup = 0.5 × 48 = 24 teaspoons, and ¾ cup = 0.75 × 48 = 36 teaspoons. This converter handles decimal and fractional cup values automatically.
This converter measures volume, not weight. Cups and teaspoons are volume units, so the conversion ratio stays the same regardless of ingredient — 1 cup always equals 48 teaspoons by volume. However, the weight (grams) of 1 cup will differ between flour, sugar, butter, and other ingredients.
Half a cup (0.5 cups) equals 24 US teaspoons. In Imperial measurements, half an Imperial cup equals approximately 28.8 Imperial teaspoons.
