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 Cubic Meter
The cubic meter is the SI-derived unit of volume. One cubic meter equals 1,000 liters. Engineering, shipping containers, and scientific volumes often use m³.
How to convert cubic inches to cubic meters
1 cubic inches is equal to 0.000016387064 cubic meter:
1 in3 = (0.016387064 L ÷ 1000 L) m3 = 0.000016387064 m3
Each cubic inches is defined as 0.016387064 L and each cubic meter as 1000 L, so one in3 equals 0.016387064 ÷ 1000 m3 = 0.000016387064 m3.
Let V(in3) be the numeric value of the same volume measured in Cubic Inches (in3), and V(m3) the value in Cubic Meter (m3). Then:
V(m3) = V(in3) × (0.016387064 / 1000)
Equivalently, divide by how many in3 fit into one m3 (liters per m3 divided by liters per in3):
V(m3) = V(in3) ÷ 61023.74409473228297
Or: cubic meter = cubic inches ÷ 61023.74409473228297
Examples
Example #1: Convert 20 in3 to cubic meter
20 in3 = 20 in3 × (0.016387064/1000) m3 = 0.0003277413 m3
20 in3 = 20 in3 ÷ 61023.74409473228297 = 0.0003277413 m3
Example #2: Convert 50 in3 to cubic meter
50 in3 = 50 in3 × (0.016387064/1000) m3 = 0.0008193532 m3
50 in3 = 50 in3 ÷ 61023.74409473228297 = 0.0008193532 m3
Summary
To convert Cubic Inches to Cubic Meter, multiply the value in in3 by the ratio of liters per in3 divided by liters per m3. Equivalently: value_m3 = value_in3 × (0.016387064 / 1000). Numerically, 1 in3 equals 0.000016387064 m3.
Relationship context
You are converting between US customary fluid / volume (Cubic Inches) and metric (SI) (Cubic Meters). US and UK fluid measures differ (gallons, ounces, tablespoons); metric liters and cubic meters align with SI. The numeric factor used here is 1.638706e-5.
