تحويل الملعقة الصغيرة إلى ملليلتر: الطبخ والطب والخبز

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.
