How to convert teaspoons (us) to fluid ounces (us)
1 teaspoon (us) is equal to 0.16666666666667 fluid ounce (us):
1 tsp = (0.00492892159375 L ÷ 0.0295735295625 L) floz = 0.16666666666667 floz
Each teaspoon (us) is defined as 0.00492892159375 L and each fluid ounce (us) as 0.0295735295625 L, so one tsp equals 0.00492892159375 ÷ 0.0295735295625 floz = 0.16666666666667 floz.
Let V(tsp) be the numeric value of the same volume measured in Teaspoon (US) (tsp), and V(floz) the value in Fluid Ounce (US) (floz). Then:
V(floz) = V(tsp) × (0.00492892159375 / 0.0295735295625)
Equivalently, divide by how many tsp fit into one floz (liters per floz divided by liters per tsp):
V(floz) = V(tsp) ÷ 6
Or: fluid ounce (us) = teaspoon (us) ÷ 6
Examples
Example #1: Convert 20 tsp to fluid ounce (us)
20 tsp = 20 tsp × (0.00492892159375/0.0295735295625) floz = 3.3333333333 floz
20 tsp = 20 tsp ÷ 6 = 3.3333333333 floz
Example #2: Convert 50 tsp to fluid ounce (us)
50 tsp = 50 tsp × (0.00492892159375/0.0295735295625) floz = 8.3333333333 floz
50 tsp = 50 tsp ÷ 6 = 8.3333333333 floz
Summary
To convert Teaspoon (US) to Fluid Ounce (US), multiply the value in tsp by the ratio of liters per tsp divided by liters per floz. Equivalently: value_floz = value_tsp × (0.00492892159375 / 0.0295735295625). Numerically, 1 tsp equals 0.16666666666666666 floz.
