Medicine Dosing: Why Teaspoons Matter
Children's medicine is often prescribed in teaspoons (1 tsp = 5 mL). An adult dose of 1 fl oz = 6 tsp = 30 mL. Using the correct conversion prevents dangerous under-dosing or overdosing. Medical professionals recommend using calibrated syringes over kitchen teaspoons, which can vary from 3 to 7 mL per spoonful.
Flavoring Extracts and Concentrates
Vanilla extract, hot sauce, and concentrated flavorings are sold in fluid ounce bottles (typically 1–4 oz) but used by the teaspoon. Knowing that a 2 oz bottle contains 12 teaspoons helps you estimate how long a bottle will last: at 1 tsp per recipe, that is 12 uses per bottle. A 4 oz bottle = 24 teaspoons, offering better value per teaspoon.
Key Takeaways
- 1 fluid ounce = 6 teaspoons exactly.
- Multiply fluid ounces by 6 to get teaspoons.
- 1 fl oz = 2 tbsp = 6 tsp.
- Medicine: 1 tsp = 5 mL; 1 fl oz = 30 mL = 6 tsp.
- A 2 oz extract bottle = 12 teaspoon servings.
- Always use calibrated measures for accurate medicine dosing.
