Milliliters to teaspoons formula
tsp = mL ÷ 4.928921594
Take the value in milliliters.
Divide it by 4.928921594 (the number of milliliters in one teaspoon).
Example: 250 mL ÷ 4.928921594 = 50.721 tsp.
Reverse formula (teaspoons to milliliters): mL = tsp × 4.928921594. Example: 48.6922 tsp × 4.928921594 = 240 mL.
Quick mental estimate: divide by about 4.9. For exact answers use the converter above.
