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 (UK)
The UK teaspoon is smaller than many US teaspoons; this tool uses the liter-based UK teaspoon factor from the shared table.
How to convert cubic inches to teaspoons (uk)
1 cubic inches is equal to 3.46046414391244 teaspoon (uk):
1 in3 = (0.016387064 L ÷ 0.004735510416667 L) uktsp = 3.46046414391244 uktsp
Each cubic inches is defined as 0.016387064 L and each teaspoon (uk) as 0.004735510416667 L, so one in3 equals 0.016387064 ÷ 0.004735510416667 uktsp = 3.46046414391244 uktsp.
Let V(in3) be the numeric value of the same volume measured in Cubic Inches (in3), and V(uktsp) the value in Teaspoon (UK) (uktsp). Then:
V(uktsp) = V(in3) × (0.016387064 / 0.004735510416667)
Equivalently, divide by how many in3 fit into one uktsp (liters per uktsp divided by liters per in3):
V(uktsp) = V(in3) ÷ 0.28897857582463
Or: teaspoon (uk) = cubic inches ÷ 0.28897857582463
Examples
Example #1: Convert 20 in3 to teaspoon (uk)
20 in3 = 20 in3 × (0.016387064/0.004735510416667) uktsp = 69.2092828782 uktsp
20 in3 = 20 in3 ÷ 0.28897857582463 = 69.2092828782 uktsp
Example #2: Convert 50 in3 to teaspoon (uk)
50 in3 = 50 in3 × (0.016387064/0.004735510416667) uktsp = 173.023207196 uktsp
50 in3 = 50 in3 ÷ 0.28897857582463 = 173.023207196 uktsp
Summary
To convert Cubic Inches to Teaspoon (UK), multiply the value in in3 by the ratio of liters per in3 divided by liters per uktsp. Equivalently: value_uktsp = value_in3 × (0.016387064 / 0.004735510416667). Numerically, 1 in3 equals 3.4604641439124375 uktsp.
Relationship context
You are converting between US customary fluid / volume (Cubic Inches) 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 3.460464e+0.
