If there are 10 mg per ml how many teaspoon is 140 mg?

Answer 1

Concentration = 10 mg/ml

140 mg = 140mg/10 mg/ml = 14 ml

1 Teaspoonful = 5 ml

14 ml = 2.8 Teaspoonfuls ~ 3 Teaspoonfuls

However, I don't know the accuracy you required. If you need the exact volume, 2.8 Teaspoonfuls are not practical. Then you have to convert 0.8 Teaspoon into drops.

0.8 Teaspoon = 0.8x5 ml = 4 ml

1 ml = 15 drops

4 ml = 4x15 = 60 drops

Then the volume is 2 teaspoonfuls and 60 drops.

Here also you see counting 60 drops is inconvenient.

Then better to take the volume of 3 teaspoonfuls and remove a volume equivalent to 0.2 teaspoons.

0.2 teaspoonful = 0.2 x 5 ml = 1 ml = 15 drops

Then;

3 teaspoonfuls minus 15 drops.
