Milliliters and teaspoons for small volumes
Teaspoons are the smallest standard kitchen volume measure in U.S. cooking, while milliliters serve the same role in metric systems. The U.S. teaspoon is approximately 4.929 mL, which is slightly less than the widely used 5 mL metric teaspoon. This small difference rarely matters in cooking but can be significant for medicine dosing — always use the product's measuring device or a marked syringe for medications. This converter is most useful for adapting metric recipes to U.S. kitchen tools and vice versa.
