Convert cups to teaspoons for precise cooking and baking measurements. Accurate calculator with conversion formulas, real recipe examples, and professional kitchen tips.
1 cup equals 48 teaspoon
Formula: tsp = cup × 48.0000
Converting cups to teaspoons is essential for recipe accuracy and scaling. With 1 cup equaling exactly 48 teaspoons, precision matters significantly in baking where ingredient ratios directly affect texture, rise, and flavor. Whether you're halving a recipe, adapting international cookbooks, or measuring specialty ingredients, understanding this conversion prevents costly kitchen failures.
In baking, a 5% measurement error—just 2.4 teaspoons in a cup—can transform a perfect cake into a dense failure or dry cookies into crispy disasters. Professional chefs and home cooks alike rely on this conversion for recipe scaling, ingredient substitution, and adapting measurements across different measurement systems. Accurate conversions ensure consistent results every time you cook.
Professional bakers use cup-to-teaspoon conversions when scaling recipes, measuring leavening agents, and adapting traditional recipes for commercial production. Pastry chefs require precise measurements for delicate ratios in croissants, macarons, and custards where 1 teaspoon difference affects the entire batch. Culinary schools teach this conversion as a fundamental skill.
Nutritionists, dietitians, and healthcare professionals use cup-to-teaspoon conversions when prescribing precise ingredient measurements for therapeutic diets, allergen-free recipes, and medical nutritional therapy. Patients with conditions like diabetes or hypertension require exact sodium or sugar measurements, making accurate conversions critical for health outcomes.

Exactly 48 teaspoons equal 1 US cup. This is the standard measurement used in American cooking, baking, and recipe development. If you're using UK Imperial measurements, 1 UK cup equals approximately 48 UK teaspoons (47.99 to be precise, but typically rounded to 48 for practical cooking). Always verify which measurement system your recipe uses—American recipes use US cups and teaspoons, while older British recipes may use Imperial measurements.
Cups are more practical for measuring larger quantities because 48 small teaspoons would be tedious and error-prone. Cups reduce measuring steps and improve consistency—one scoop of flour is simpler than measuring 48 individual teaspoons. However, for small quantities like vanilla extract (typically 1-2 teaspoons) or leavening agents like baking powder (usually 1-3 teaspoons), teaspoons are more precise and prevent over-dosing. Professional recipes often use weight in grams for maximum accuracy, but home cooks rely on this cup-to-teaspoon hierarchy for practical measurements.
