While this converter can help with volume conversions, always follow the exact dosage instructions provided by your healthcare provider or pharmacist. Medical dosages require precision and should never be approximated or converted without professional guidance. Use the dosing device that comes with the medication.
Use proper measuring spoons, not regular eating spoons. For liquids, fill the spoon to the brim. For dry ingredients, level off with a straight edge. Standard measuring spoons come in sets: 1/4 tsp, 1/2 tsp, 1 tsp, and 1 tablespoon.
