About Tablespoon (US)
The US tablespoon is 1/2 US fluid ounce (about 14.7868 ml). US recipes use tablespoons for cooking volumes.
About Cubic Inches
The cubic inch is the volume of a cube one inch on a side. Engine displacement in the US and small volumes in machining use cubic inches.
How to convert tablespoons (us) to cubic inches
1 tablespoon (us) is equal to 0.90234375 cubic inches:
1 tbsp = (0.01478676478125 L ÷ 0.016387064 L) in3 = 0.90234375 in3
Each tablespoon (us) is defined as 0.01478676478125 L and each cubic inches as 0.016387064 L, so one tbsp equals 0.01478676478125 ÷ 0.016387064 in3 = 0.90234375 in3.
Let V(tbsp) be the numeric value of the same volume measured in Tablespoon (US) (tbsp), and V(in3) the value in Cubic Inches (in3). Then:
V(in3) = V(tbsp) × (0.01478676478125 / 0.016387064)
Equivalently, divide by how many tbsp fit into one in3 (liters per in3 divided by liters per tbsp):
V(in3) = V(tbsp) ÷ 1.10822510822511
Or: cubic inches = tablespoon (us) ÷ 1.10822510822511
Examples
Example #1: Convert 20 tbsp to cubic inches
20 tbsp = 20 tbsp × (0.01478676478125/0.016387064) in3 = 18.046875 in3
20 tbsp = 20 tbsp ÷ 1.10822510822511 = 18.046875 in3
Example #2: Convert 50 tbsp to cubic inches
50 tbsp = 50 tbsp × (0.01478676478125/0.016387064) in3 = 45.1171875 in3
50 tbsp = 50 tbsp ÷ 1.10822510822511 = 45.1171875 in3
Summary
To convert Tablespoon (US) to Cubic Inches, multiply the value in tbsp by the ratio of liters per tbsp divided by liters per in3. Equivalently: value_in3 = value_tbsp × (0.01478676478125 / 0.016387064). Numerically, 1 tbsp equals 0.90234375 in3.
