Volume is the category where the US and imperial systems diverge most damagingly. Gallons, quarts, pints and fluid ounces all exist in two sizes that differ by up to 20%, and nothing in the name warns you which one a figure uses. Recipes, fuel economy figures and container capacities all cross borders regularly, so it is worth checking which system a source is using before converting rather than after.
ml to tsp formula
To go the other way, use milliliter = us teaspoon ÷ 0.20288414.
About these units
A millilitre is exactly one cubic centimetre. Because one millilitre of water weighs one gram, the unit doubles as a rough mass measure in the kitchen.
A US teaspoon is 4.93 millilitres, rounded to 5 ml almost everywhere in practice. Australian tablespoons are the outlier at 20 ml rather than 15.
Milliliter is also written millilitre, millilitres, milliliters and cc. US Teaspoon is also written teaspoons and tsps.
