How to convert teaspoons (us) to gallons (uk)
1 teaspoon (us) is equal to 0.0010842111779 gallon (uk):
1 tsp = (0.00492892159375 L ÷ 4.54609 L) ukgal = 0.0010842111779 ukgal
Each teaspoon (us) is defined as 0.00492892159375 L and each gallon (uk) as 4.54609 L, so one tsp equals 0.00492892159375 ÷ 4.54609 ukgal = 0.0010842111779 ukgal.
Let V(tsp) be the numeric value of the same volume measured in Teaspoon (US) (tsp), and V(ukgal) the value in Gallon (UK) (ukgal). Then:
V(ukgal) = V(tsp) × (0.00492892159375 / 4.54609)
Equivalently, divide by how many tsp fit into one ukgal (liters per ukgal divided by liters per tsp):
V(ukgal) = V(tsp) ÷ 922.32954278772866
Or: gallon (uk) = teaspoon (us) ÷ 922.32954278772866
Examples
Example #1: Convert 20 tsp to gallon (uk)
20 tsp = 20 tsp × (0.00492892159375/4.54609) ukgal = 0.0216842236 ukgal
20 tsp = 20 tsp ÷ 922.32954278772866 = 0.0216842236 ukgal
Example #2: Convert 50 tsp to gallon (uk)
50 tsp = 50 tsp × (0.00492892159375/4.54609) ukgal = 0.0542105589 ukgal
50 tsp = 50 tsp ÷ 922.32954278772866 = 0.0542105589 ukgal
