How to Convert Cubic Inches to Liters

To convert a measurement in cubic inches to a measurement in liters, multiply the volume by the following conversion ratio: 0.016387 liters/cubic inch.

Since one cubic inch is equal to 0.016387 liters, you can use this simple formula to convert:

liters = cubic inches × 0.016387

The volume in liters is equal to the volume in cubic inches multiplied by 0.016387.

For example, here's how to convert 5 cubic inches to liters using the formula above.

liters = (5 in³ × 0.016387) = 0.081935 L

Cubic inches and liters are both units used to measure volume. Keep reading to learn more about each unit of measure.
