The teaspoon
The US teaspoon equals 1/3 of a US tablespoon, or about 4.929 mL. The metric teaspoon (used on most non-US nutrition labels) is exactly 5 mL — close enough that you can substitute freely in cooking but not in precise dosing.
75 Teaspoons to Milliliters
75 tsp = 369.669 mL (teaspoon → milliliter)
75 tsp = 369.669 mL
75 teaspoons (tsp) equals 369.669 milliliters (mL). The conversion uses the exact factor 4.92892: 75 × 4.92892 = 369.669.

When to use teaspoons → milliliters
US teaspoons to millilitres multiplies by 4.92892 (1 US tsp = 4.92892 mL), universally rounded to 5 mL in cooking and medicine. A 5 mL medicine dose is one level teaspoon, though kitchen teaspoons vary enough that pharmacies supply a 5 mL oral syringe for accuracy. Three teaspoons make one tablespoon (14.79 mL). For baking leaveners and salt, the small absolute volumes mean the rounding to 5 mL rarely changes the result.
Paediatric and veterinary dosing instructions printed in teaspoons get converted to millilitres to match the graduated oral syringe that actually ships with the medication. 1 tsp is 4.929 mL, commonly rounded to 5 mL on packaging for simplicity; 2 tsp is 9.858 mL; 0.5 tsp is 2.465 mL. Because pharmacies round the “standard teaspoon” to a clean 5 mL for dosing purposes, always follow the syringe markings on the package rather than converting the true 4.929 mL teaspoon value yourself.
