About Fluid Ounce (US)
The US fluid ounce is 1/128 of a US gallon (about 29.5735 ml). US nutrition labels and recipes use fluid ounces for liquids.
About Teaspoon (US)
The US teaspoon is 1/6 US fluid ounce (about 4.9289 ml). US recipes use teaspoons for spices and small liquid amounts.
How to convert fluid ounces (us) to teaspoons (us)
1 fluid ounce (us) is equal to 6 teaspoon (us):
1 floz = (0.0295735295625 L ÷ 0.00492892159375 L) tsp = 6 tsp
Each fluid ounce (us) is defined as 0.0295735295625 L and each teaspoon (us) as 0.00492892159375 L, so one floz equals 0.0295735295625 ÷ 0.00492892159375 tsp = 6 tsp.
Let V(floz) be the numeric value of the same volume measured in Fluid Ounce (US) (floz), and V(tsp) the value in Teaspoon (US) (tsp). Then:
V(tsp) = V(floz) × (0.0295735295625 / 0.00492892159375)
Equivalently, divide by how many floz fit into one tsp (liters per tsp divided by liters per floz):
V(tsp) = V(floz) ÷ 0.16666666666667
Or: teaspoon (us) = fluid ounce (us) ÷ 0.16666666666667
Examples
Example #1: Convert 20 floz to teaspoon (us)
20 floz = 20 floz × (0.0295735295625/0.00492892159375) tsp = 120 tsp
20 floz = 20 floz ÷ 0.16666666666667 = 120 tsp
Example #2: Convert 50 floz to teaspoon (us)
50 floz = 50 floz × (0.0295735295625/0.00492892159375) tsp = 300 tsp
50 floz = 50 floz ÷ 0.16666666666667 = 300 tsp
Summary
To convert Fluid Ounce (US) to Teaspoon (US), multiply the value in floz by the ratio of liters per floz divided by liters per tsp. Equivalently: value_tsp = value_floz × (0.0295735295625 / 0.00492892159375). Numerically, 1 floz equals 6 tsp.
