Convert teaspoons to milliliters accurately for recipes, medication dosing, and baking. Essential guide with real-world examples and precise conversion factors.
1 teaspoon equals 4.92892490290018 milliliter
Formula: mL = tsp × 4.92892
Converting teaspoons to milliliters is essential for anyone following recipes, administering medication, or baking. One teaspoon equals approximately 4.92892 milliliters in the US measurement system, though metric teaspoons use 5 milliliters. Understanding this conversion prevents costly recipe failures and ensures accurate medication dosing.
Precision in volume measurement directly impacts recipe success, medication safety, and baking consistency. A single teaspoon error in medication dosing can result in 5 milliliters of difference—potentially dangerous for pediatric doses. In baking, incorrect measurements can ruin batches worth $15-30. International recipe sharing requires accurate conversion between imperial and metric systems.
Healthcare professionals and patients must convert teaspoon measurements to milliliters for accurate medication dosing. Pediatric medications, liquid supplements, and over-the-counter remedies frequently use teaspoon measurements on packaging, but clinical protocols require milliliter precision. Incorrect conversions can lead to overdosing or underdosing, making accuracy critical for patient safety.
Professional chefs and bakers frequently convert between teaspoons and milliliters when scaling recipes internationally or following European standards. Precise measurements are critical in baking where ratios determine texture and rise. Commercial kitchens in multicultural settings must accommodate both imperial and metric recipe formats, requiring accurate conversions for consistency.

One US teaspoon equals 4.92892 milliliters precisely. However, one metric teaspoon equals exactly 5 milliliters. The difference exists because the US teaspoon is defined as 1/6 US fluid ounce, while the metric teaspoon is a standard metric unit. For casual cooking, using 5 mL is acceptable, but for medication and precision baking, use 4.92892 mL for US recipes and 5 mL for metric/European recipes.
The inconsistency stems from different measurement systems. US recipes were developed using imperial measurements (teaspoons), while European and international recipes use metric (milliliters). A US teaspoon (4.92892 mL) is slightly smaller than a metric teaspoon (5 mL). When converting a recipe with multiple teaspoons, these small differences compound. A recipe with 8 teaspoons would be 39.43 mL (US) versus 40 mL (metric)—a small but measurable difference in baking outcomes.
