How to convert teaspoons (us) to fluid ounces (uk)
1 teaspoon (us) is equal to 0.17347378846437 fluid ounce (uk):
1 tsp = (0.00492892159375 L ÷ 0.0284130625 L) ukfloz = 0.17347378846437 ukfloz
Each teaspoon (us) is defined as 0.00492892159375 L and each fluid ounce (uk) as 0.0284130625 L, so one tsp equals 0.00492892159375 ÷ 0.0284130625 ukfloz = 0.17347378846437 ukfloz.
Let V(tsp) be the numeric value of the same volume measured in Teaspoon (US) (tsp), and V(ukfloz) the value in Fluid Ounce (UK) (ukfloz). Then:
V(ukfloz) = V(tsp) × (0.00492892159375 / 0.0284130625)
Equivalently, divide by how many tsp fit into one ukfloz (liters per ukfloz divided by liters per tsp):
V(ukfloz) = V(tsp) ÷ 5.7645596424233
Or: fluid ounce (uk) = teaspoon (us) ÷ 5.7645596424233
Examples
Example #1: Convert 20 tsp to fluid ounce (uk)
20 tsp = 20 tsp × (0.00492892159375/0.0284130625) ukfloz = 3.4694757693 ukfloz
20 tsp = 20 tsp ÷ 5.7645596424233 = 3.4694757693 ukfloz
Example #2: Convert 50 tsp to fluid ounce (uk)
50 tsp = 50 tsp × (0.00492892159375/0.0284130625) ukfloz = 8.6736894232 ukfloz
50 tsp = 50 tsp ÷ 5.7645596424233 = 8.6736894232 ukfloz
Summary
To convert Teaspoon (US) to Fluid Ounce (UK), multiply the value in tsp by the ratio of liters per tsp divided by liters per ukfloz. Equivalently: value_ukfloz = value_tsp × (0.00492892159375 / 0.0284130625). Numerically, 1 tsp equals 0.17347378846437267 ukfloz.
Relationship context
