Converting cubic inches to liters is essential for automotive professionals, engineers, and machinery manufacturers. With 1 cubic inch equaling precisely 0.0163871 liters, accurate conversion is critical for engine specifications, displacement calculations, and international technical documentation. This conversion bridges American imperial measurements with the metric system used globally.
Engine displacement directly affects performance, fuel efficiency, emissions compliance, and insurance classifications. A single cubic inch miscalculation on a 350 cubic inch engine (5.735 liters) can lead to incorrect horsepower ratings, failed emissions tests, or compliance violations. International regulations require metric specifications, making precise conversion essential for vehicle certification and cross-border sales.
Engine displacement measured in cubic inches must be converted to liters for international specifications, emissions testing, and regulatory compliance. Manufacturers use this conversion for engine development, performance ratings, and vehicle certification across different markets. Precision directly impacts horsepower calculations, fuel economy ratings, and compliance with international standards.
Hydraulic cylinders, pumps, and accumulators often have displacement specifications in cubic inches, particularly in North American industrial equipment. Converting to liters ensures compatibility with international fluid power standards, component selection, and system design calculations. Flow rates and pressure ratings depend on accurate volume measurements.

This cubic inch to liter converter uses high-precision conversion factors to ensure accurate results for professional and academic use.
Our calculator provides results with up to 10 decimal places for maximum accuracy.
Exactly 0.0163871 liters. This precise conversion comes from the relationship between inch and centimeter: 1 inch = 2.54 cm exactly, so 1 cubic inch = 2.54³ = 16.387064 cubic centimeters = 0.0163871 liters. For quick mental math, remember that 61 cubic inches ≈ 1 liter, so divide cubic inches by 61 for an approximate conversion.
The United States never officially adopted the metric system, so American automotive manufacturers continued using cubic inches for engine displacement specifications. This tradition persists in the classic car market and performance aftermarket. However, modern American vehicles sold internationally must meet metric standards. The conversion factor 0.0163871 bridges this historical measurement difference between American and global automotive standards.
