How to convert tablespoons (us) to tablespoons (uk)
1 tablespoon (us) is equal to 1.04084273078624 tablespoon (uk):
1 tbsp = (0.01478676478125 L ÷ 0.01420653125 L) uktbsp = 1.04084273078624 uktbsp
Each tablespoon (us) is defined as 0.01478676478125 L and each tablespoon (uk) as 0.01420653125 L, so one tbsp equals 0.01478676478125 ÷ 0.01420653125 uktbsp = 1.04084273078624 uktbsp.
Let V(tbsp) be the numeric value of the same volume measured in Tablespoon (US) (tbsp), and V(uktbsp) the value in Tablespoon (UK) (uktbsp). Then:
V(uktbsp) = V(tbsp) × (0.01478676478125 / 0.01420653125)
Equivalently, divide by how many tbsp fit into one uktbsp (liters per uktbsp divided by liters per tbsp):
V(uktbsp) = V(tbsp) ÷ 0.96075994040388
Or: tablespoon (uk) = tablespoon (us) ÷ 0.96075994040388
Examples
Example #1: Convert 20 tbsp to tablespoon (uk)
20 tbsp = 20 tbsp × (0.01478676478125/0.01420653125) uktbsp = 20.8168546157 uktbsp
20 tbsp = 20 tbsp ÷ 0.96075994040388 = 20.8168546157 uktbsp
Example #2: Convert 50 tbsp to tablespoon (uk)
50 tbsp = 50 tbsp × (0.01478676478125/0.01420653125) uktbsp = 52.0421365393 uktbsp
50 tbsp = 50 tbsp ÷ 0.96075994040388 = 52.0421365393 uktbsp
Summary
To convert Tablespoon (US) to Tablespoon (UK), multiply the value in tbsp by the ratio of liters per tbsp divided by liters per uktbsp. Equivalently: value_uktbsp = value_tbsp × (0.01478676478125 / 0.01420653125). Numerically, 1 tbsp equals 1.040842730786236 uktbsp.
Relationship context
You are converting between US customary fluid / volume (Tablespoons (US)) and UK imperial fluid / volume (Tablespoons (UK)). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 1.040843e+0.
