Cc to Liter

Metric Volumetric & NIST SP 811 Standards

The liter is a non-SI metric unit accepted for use with the International System of Units (SI). By definition, 1 Liter equals exactly 1,000 Cubic Centimeters (CC).

Primary Volumetric Ratios

• 1 Liter: 1,000 CC = 1,000 mL = 0.001 m^3

• 1 CC: 0.001 Liter = 1 mL = 1 cm^3

• 1 US Fluid Ounce: 29.5735 CC = 0.02957 L

• 1 US Gallon: 3,785.41 CC = 3.7854 L

• 1 Cubic Inch (CID): 16.3871 CC = 0.01639 L

How to Use This Calculator

Enter your Volume Value to Convert (e.g. 2000.0) and Conversion Direction — choose from CC to Liters (cc → L / divide by 1,000), Liters to CC (L → cc / multiply by 1,000). Results update instantly as you type — adjust any value to compare scenarios.

Worked Example

A 2,000 cc motorcycle or car engine has a displacement of exactly 2.0 Liters (122 CID), producing 2,000 milliliters of total cylinder combustion sweep.

Understanding Your Result

Unit conversion precision: round to the same number of significant figures as your original measurement. Converting 6 feet to meters gives 1.8288 m — but if your measurement was approximate (±1 inch), expressing more than 2 decimal places is false precision. For international trade and technical specifications, SI units (meters, kilograms, liters) are the standard. US customary units (feet, pounds, gallons) differ from Imperial UK units: 1 US gallon = 3.785 L vs. 1 UK gallon = 4.546 L.
