About Converting Liters to Cubic inches
Liter and Cubic inch appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Liter is most often used for beverage, fuel, and liquid product packaging worldwide.
Formula
cubic inches = liters × 61.0237440947
This factor comes from each unit's defined relationship to the category's base unit: 1 liter equals 0.001 base units, and 1 cubic inch equals 0.000016387064 base units, so dividing one by the other gives the direct liter-to-cubic inch factor of 61.0237440947.
Simple example
1 L × 61.02374409 = 61.02374409 in3
1 liter = 61.02374409 cubic inches.
Real-world example
10 L × 61.02374409 = 610.2374409 in3
10 liters = 610.2374409 cubic inches.

- Laboratory and scientific volume measurement
History of the Liter
The liter was introduced with the French metric system in 1795, originally defined as the volume of one kilogram of pure water at its freezing point — tying volume, mass, and the meter together.
Between 1901 and 1964, the liter was briefly redefined as the volume of exactly one kilogram of water at its maximum density (about 4 °C), which made it very slightly larger than a cubic decimeter. It was redefined back to exactly one cubic decimeter in 1964, the definition still used today.
Historical origin. Liter was not the invention of a single named person; it developed through the process described above.
