About Teaspoon (US) (tsp (US))
Definition
The US teaspoon is a unit of culinary volume equal to 1/3 of a US tablespoon, or approximately 4.929 milliliters.
Mathematical Relationship
1 US tsp = 1/3 US tbsp = 1/6 US fl oz = 1/48 US cup ≈ 4.929 mL.
Conversion Formula
To mL: multiply by 4.929. To UK teaspoons: multiply by 0.832674. To tablespoons (US): divide by 3.
Practical Applications
Cooking and baking recipes, measuring medicine doses, adding spices, sugar or salt, and child medication dosing.
Interesting Facts
The US teaspoon is slightly smaller than the metric teaspoon (5 mL). The phrase 'a teaspoon of sugar' equals about 4 grams.
Common Mistakes
Using a regular eating spoon instead of a measuring teaspoon — actual teaspoons vary widely. Always use a calibrated spoon.
Educational Tips
3 tsp = 1 tbsp. 48 tsp = 1 cup. For mL conversion, remember 1 tsp ≈ 5 mL (the metric teaspoon is exactly 5 mL).
About Drop (gtt)
Definition
The drop (medical/pharmacological) is an approximate unit of volume equal to about 0.05 milliliters, or 50 microliters.
Mathematical Relationship
1 drop ≈ 0.05 mL = 50 µL ≈ 1/20 mL. Approximately 20 drops = 1 mL (for water-like liquids).
Conversion Formula
To mL: multiply by 0.05 (approximate). To µL: multiply by 50. 20 drops ≈ 1 mL for aqueous solutions.
Practical Applications
Eye drop medication, ear drops, essential oil use, flavoring extracts in cooking, and IV drip rate measurement.
Interesting Facts
The size of a drop varies significantly: water drops from a glass dropper (~50 µL) differ from rain drops (~50,000–100,000 µL) by a factor of 1,000.
Common Mistakes
Assuming all drops are the same size — oily liquids produce larger drops than water. Always check the dropper calibration.
Educational Tips
20 drops ≈ 1 mL for water-based solutions. In IV therapy, standard drip sets deliver 10, 15, or 20 drops/mL depending on the design.
