Milliliters to Us Teaspoons
A milliliter is one thousandth of a liter, equal to one cubic centimeter, used for medicine doses and small liquid measures. A US teaspoon is about 4.93 milliliters, a standard measure in American cooking recipes. 1 mL equals ≈0.202884 tsp, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to volume, measured here against volume's base unit (L) — every other volume unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
tsp = mL × ≈0.202884
