Liquid medicine dose converter

Convert between millilitres and medicine spoons, or work out how many millilitres hold a dose in milligrams.

What do you want to work out?
Measure with the oral syringe, cup or spoon that comes with the medicine. Kitchen spoons are not accurate, and an Australian kitchen tablespoon holds 20 mL, not 15. Check the strength on the label every time: the same medicine can come in more than one strength.

Arithmetic only, not medical advice. For children, use the dose on the label or the one your doctor or pharmacist gave you.

The numbers behind it

In medicine, a teaspoon is 5 mL and a tablespoon is 15 mL. Those are the measures printed on dosing cups and spoons. Doses are safest in millilitres, which is why most labels and oral syringes use them.

To turn milligrams into millilitres, divide the dose by the strength per millilitre. A bottle of 125 mg in 5 mL holds 25 mg in each millilitre, so a 250 mg dose is 10 mL. If the label gives the strength per 1 mL, enter 1 in the mL box.
