About Cubic Inch to Liter Conversion

Converting cubic inch to liter comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using liter, or a laboratory protocol may specify volumes in cubic inch that need to be measured with equipment calibrated in liter.

In everyday use, knowing that 5 in³ = 0.08194 L and 10 in³ = 0.1639 L covers most common situations. For bulk calculations, 100 in³ = 1.639 L is a useful anchor. The reverse conversion — liter back to cubic inch — uses the factor 61.02, so 1 L = 61.02 in³.

All conversions use the internationally recognized factor of exactly 1 in³ = 0.01639 L. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.

Quick Answer

Formula: Liter = Cubic Inch × 0.0163871

Multiply any cubic inch value by 0.0163871 to get liter. One cubic inch equals 0.0163871 L.

Reverse: Cubic Inch = Liter × 61.02361

Worked Examples

One liter
61.02 in³ × 0.0163871 = 0.99994084 L
61.02 in³ = 1 liter — the base reference.
One US gallon
231 in³ × 0.0163871 = 3.7854201 L
231 in³ = exactly 1 US gallon = 3.785 liters — a legally defined equivalence.
One cubic inch
1 in³ × 0.0163871 = 0.0163871 L
1 in³ = 0.01639 liters — volume of a small marble.
Standard soda can
21.7 in³ × 0.0163871 = 0.35560007 L
A 12 fl oz soda can displaces about 21.7 in³ = 0.355 liters.

Frequently Asked Questions

About Cubic Inch and Liter

Cubic Inch (in³)

The cubic inch is the volume of a cube with one-inch sides, equal to exactly 16.387064 mL. It belongs to US customary and British Imperial systems, in practical use since the 17th century.

Cubic inches appear most often in engine displacement for small engines and in precision machining for material volume calculations.

Interesting fact: A standard 12-fluid-ounce US soda can has a volume of about 21.7 cubic inches.

Liter (L)

The liter was introduced by the French metric system in 1793, defined as the volume of one kilogram of pure water at 4°C. The word derives from the older French unit litron, from Medieval Latin litra. It was redefined in 1964 as exactly 1 cubic decimeter.

France adopted the liter as part of revolutionary metric standardization, spreading across Europe with Napoleonic expansion. Today it is the standard unit for liquids in most of the world, from soda bottles to fuel pumps.

Interesting fact: A liter of water at 4°C weighs almost exactly 1 kilogram, which is why the kilogram was originally defined through it.
