Convert Liter to Cubic Inch (L → in³)

Converting liters to cubic inches is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in liters

   Start with the number of liters (L) you want to convert.
2. 2
   Multiply by 61.023744

   The conversion factor from L to in³ is 61.023744. Multiply your value by this number.
3. 3
   Read the result in cubic inches

   The result is your value in cubic inches (in³).

Multiply the value in liters by 61.023744. For the reverse direction, multiply by 0.016387.

• ✓1 L = 1000 ml = 1 dm³ = 0.001 m³ exactly.
• ✓1 L of water weighs 1 kg at 4 °C — use for quick mass estimates.
• ✓Fuel economy in Europe is litres per 100 km; lower is better. US uses mpg where higher is better.

• ✗Confusing L (litre) with l (lowercase), since lowercase l can be mistaken for digit 1. Capital L is preferred.
• ✗Mixing litres and US gallons in fuel economy discussions.
• ✗Writing engine displacement in ml instead of L — 1500 cc = 1.5 L.

What is the Liter?

The liter equals exactly 1 cubic decimeter (1 dm³ = 0.001 m³) and is the everyday metric unit for liquids worldwide. Adopted as part of the metric system in the 1790s, the liter is used universally for beverages, fuel, household chemicals, and cooking liquids — except in the United States where gallons and fluid ounces dominate. The liter has special connection to mass: pure water at 4°C has almost exactly 1 kg per liter, a relationship designed into the metric system. Soda, milk, and water bottles in metric countries come in 0.5 L, 1 L, 1.5 L, and 2 L sizes. The liter relates to the milliliter (1,000 mL = 1 L), the cubic meter (1,000 L = 1 m³), the US gallon (1 L ≈ 0.264 gal), and the UK gallon (1 L ≈ 0.220 imp gal). Although not strictly an SI base unit, the liter is one of the most-used metric units globally.

• Bottled beverages and milk in Europe
• Petrol and diesel pricing in metric countries
• Engine displacement (car engines rated in litres)

What is the Cubic Inch?

The cubic inch equals exactly 16.387064 cubic centimeters and is the traditional American unit for engine displacement and small-volume manufacturing measurements. Classic American muscle cars were famously identified by their cubic-inch engine size: the Ford 'Boss 429' had a 429-cubic-inch (7.0-liter) V8, and the Chevrolet 'Big Block 454' was 7.4 liters. Modern American automakers have transitioned mostly to liter-based naming (e.g., 'Hemi 5.7'), but the cubic inch persists in vintage car culture and aviation engines. It is also used for printer-paper coverage and industrial tolerances. The cubic inch relates to the cubic foot (1,728 in³ = 1 ft³), the cubic centimeter (1 in³ ≈ 16.39 cm³), the milliliter (1 in³ ≈ 16.39 mL), and the US fluid ounce (1 fl oz ≈ 1.805 in³).
