CC to Liter Converter — Cubic Centimetres to Litres
Instantly convert cc (cubic centimetres) to litres — or litres to cc — with exact SI factors. Also shows millilitres, US gallons, fluid ounces and cups in one step.
Input unit
1 litre = 1,000 cc = 1,000 mL — exact by SI definition
- 1
Input volume (cc = mL)
1,000 - 2
Litres = cc ÷ 1,000
1,000 ÷ 1,000 = 1
How does this calculator work?
cc ÷ 1,000 = litres. litres × 1,000 = cc. Both conversions are exact (SI definition). Examples: 500 cc = 0.5 L; 2,500 cc = 2.5 L; 1 L = 1,000 cc = 1,000 mL. cc and mL are identical units. US conversions: 1 L ≈ 0.264 gal; 1 fl oz ≈ 29.57 cc.
Formula
How this is calculated
The conversion between cubic centimetres and litres is exact and follows directly from SI definitions. One litre is defined as one cubic decimetre (1 dm³ = 10 cm × 10 cm × 10 cm = 1,000 cm³), so 1 L = 1,000 cc with no rounding. To convert cc to litres, divide by 1,000; to convert litres to cc, multiply by 1,000. Because 1 cc = 1 mL by definition, the conversion is identical for millilitres.
Engine displacement is a common practical context: a 2.0 L engine has 2,000 cc of total cylinder volume; a 1,600 cc engine is 1.6 L. Similarly, medical doses in syringes are often expressed in cc or mL interchangeably — 5 cc of saline is exactly 5 mL.
US customary conversions are derived from the exact legal definition: 1 US gallon = 3.785 411 784 L (exact, US definition), giving 1 L ≈ 0.264 172 gallons, 1 US fl oz = 29.573 5 mL, and 1 US cup = 8 fl oz ≈ 236.588 mL. These are the values applied in this calculator.
Frequently asked questions
Exactly 1,000 cc (cubic centimetres) in one litre. This is an exact SI definition: 1 L = 1 dm³ = 1,000 cm³. There is no rounding — the conversion factor is precisely 1,000.
Yes, exactly. One cubic centimetre (1 cc = 1 cm³) equals one millilitre (1 mL) by SI definition. Doctors write mL; engineers write cc or cm³ — but they are the same volume. 1,000 cc = 1,000 mL = 1 L.
For small engines (motorcycles, lawnmowers, small-displacement cars), the numbers in cc (e.g. 125 cc, 650 cc) are more convenient than very small decimal litres (0.125 L, 0.65 L). For larger engines the litre figure is more readable (2.0 L vs. 2,000 cc). Both are equally precise.
