Water Volume Calculation


Frequently Used Equivalents

ppm (parts per million) is equivalent to one milligram per liter of water.

5ml = 1 teaspoon

20 drops = 1 ml.

60 drops = 1 teaspoon

15ml = 1 tablespoon

2 tsp. = 1 dessert spoon

2 dessert spoons = 1 tablespoon

2 tbsp. = 1 fl. oz.

8 fl. oz. = 1 cup

1 cup = 48 teaspoons

1 cup = 16 tablespoons

1 cup = 237ml.

*These figures are commonly supplied by most chart sources.  However, using a standard, pharmacist-supplied, two-milliliter eye dropper and a standard kitchen measuring teaspoon, the equivalency was found to be 3ml/tsp. and 9ml/tbsp. 

*Culinary, or food industry measuring devices and weights are different from pharmaceutical and laboratory measuring devices.
