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.
About Teaspoon (US)
The US teaspoon is 1/6 US fluid ounce (about 4.9289 ml). US recipes use teaspoons for spices and small liquid amounts.
How to convert cubic inches to teaspoons (us)
1 cubic inches is equal to 3.32467532467532 teaspoon (us):
1 in3 = (0.016387064 L ÷ 0.00492892159375 L) tsp = 3.32467532467532 tsp
Each cubic inches is defined as 0.016387064 L and each teaspoon (us) as 0.00492892159375 L, so one in3 equals 0.016387064 ÷ 0.00492892159375 tsp = 3.32467532467532 tsp.
Let V(in3) be the numeric value of the same volume measured in Cubic Inches (in3), and V(tsp) the value in Teaspoon (US) (tsp). Then:
V(tsp) = V(in3) × (0.016387064 / 0.00492892159375)
Equivalently, divide by how many in3 fit into one tsp (liters per tsp divided by liters per in3):
V(tsp) = V(in3) ÷ 0.30078125
Or: teaspoon (us) = cubic inches ÷ 0.30078125
Examples
Example #1: Convert 20 in3 to teaspoon (us)
20 in3 = 20 in3 × (0.016387064/0.00492892159375) tsp = 66.4935064935 tsp
20 in3 = 20 in3 ÷ 0.30078125 = 66.4935064935 tsp
Example #2: Convert 50 in3 to teaspoon (us)
50 in3 = 50 in3 × (0.016387064/0.00492892159375) tsp = 166.233766234 tsp
50 in3 = 50 in3 ÷ 0.30078125 = 166.233766234 tsp
Summary
To convert Cubic Inches to Teaspoon (US), multiply the value in in3 by the ratio of liters per in3 divided by liters per tsp. Equivalently: value_tsp = value_in3 × (0.016387064 / 0.00492892159375). Numerically, 1 in3 equals 3.324675324675325 tsp.
