About Gallon (US)
The US liquid gallon is defined as 231 cubic inches (about 3.78541 liters). US recipes, fuel economy, and retail liquids typically use US gallons.

How to convert gallons (us) to teaspoons (uk)
1 gallon (us) is equal to 799.36721639909115 teaspoon (uk):
1 gal = (3.78541178 L ÷ 0.004735510416667 L) uktsp = 799.36721639909115 uktsp
Each gallon (us) is defined as 3.78541178 L and each teaspoon (uk) as 0.004735510416667 L, so one gal equals 3.78541178 ÷ 0.004735510416667 uktsp = 799.36721639909115 uktsp.
Let V(gal) be the numeric value of the same volume measured in Gallon (US) (gal), and V(uktsp) the value in Teaspoon (UK) (uktsp). Then:
V(uktsp) = V(gal) × (3.78541178 / 0.004735510416667)
Equivalently, divide by how many gal fit into one uktsp (liters per uktsp divided by liters per gal):
V(uktsp) = V(gal) ÷ 0.00125098950706
Or: teaspoon (uk) = gallon (us) ÷ 0.00125098950706
Examples
Example #1: Convert 20 gal to teaspoon (uk)
20 gal = 20 gal × (3.78541178/0.004735510416667) uktsp = 15987.344328 uktsp
20 gal = 20 gal ÷ 0.00125098950706 = 15987.344328 uktsp
Example #2: Convert 50 gal to teaspoon (uk)
50 gal = 50 gal × (3.78541178/0.004735510416667) uktsp = 39968.36082 uktsp
50 gal = 50 gal ÷ 0.00125098950706 = 39968.36082 uktsp
Summary
To convert Gallon (US) to Teaspoon (UK), multiply the value in gal by the ratio of liters per gal divided by liters per uktsp. Equivalently: value_uktsp = value_gal × (3.78541178 / 0.004735510416667). Numerically, 1 gal equals 799.3672163990911 uktsp.
Relationship context
You are converting between US customary fluid / volume (Gallons (US)) and UK imperial fluid / volume (Teaspoons (UK)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 7.993672e+2.
