How many litres is 1 cc?

1 cubic centimetre (cc or cm³) equals exactly 0.001 litres (1 millilitre). This is because 1 litre is defined as 1,000 cubic centimetres. So to convert cc to litres, divide the number of cc by 1,000. For example, 500 cc equals 0.5 litres, and 2,500 cc equals 2.5 litres.

Is cc the same as mL?

Yes. One cubic centimetre (1 cc or 1 cm³) is exactly equal to one millilitre (1 mL). The two units are used interchangeably in medicine, cooking, and engineering. For example, a 500 cc volume is the same as 500 mL or 0.5 litres. The abbreviation 'cc' is particularly common in medical contexts (such as drug dosages and syringe measurements), while 'mL' is more common in food and beverage contexts.

How do I convert engine size from cc to litres?

To convert engine displacement from cc to litres, divide by 1,000. A 1,600 cc engine is 1.6 litres. A 2,000 cc engine is 2.0 litres. A 3,500 cc engine is 3.5 litres. Car manufacturers often round to one decimal place for marketing purposes, so a 1,998 cc engine is typically advertised as a 2.0-litre engine.

CC to Litre Converter

This calculator converts cubic centimetres (cc, also written cm³) into litres, and litres back into cc, using the exact SI relationship: one cubic centimetre equals precisely 0.001 litres, the same as one millilitre. Understanding this conversion matters because cc, litres and millilitres appear in different everyday contexts: car engine displacement is usually quoted in cc but marketed in litres, medical dosages and syringe volumes are measured in cc or mL, and recipes and drink containers use litres or millilitres. To use the tool, type a figure into either the cc field or the litres field, or pick a common value from the drop-down presets, which range from a 1 cc syringe dose and 5 cc teaspoon through to 250 cc cups, 500 cc bottles and 1,600 cc to 3,500 cc engine sizes. As you type, the calculator instantly returns the litres equivalent, the millilitre equivalent (identical to the cc figure), the cc equivalent of any litre amount you enter, and a plain-English verdict summarising the conversion. A reference table below the calculator lists common cc, litre and millilitre values alongside their real-world context, and a worked example shows the default 500 cc converting to 0.5 litres and 500 mL. Because the cc-to-litre relationship is a fixed mathematical definition rather than an estimate, every result shown is exact, with no rounding error introduced by the conversion itself.

How to Convert CC to Litres

One cubic centimetre (cc) is exactly one thousandth of a litre. The conversion formula is:

Litres = cc ÷ 1,000

To convert in the opposite direction:

CC = litres × 1,000

Because 1 litre is defined as 1 cubic decimetre (dm³), and 1 dm³ = 1,000 cm³, the relationship between cc and litres is exact and does not involve any rounding. The same conversion applies to millilitres: 1 cc = 1 mL, so converting cc to mL requires no calculation at all.

Worked Example

Convert 500 cc to litres:

Start with 500 cc.
Divide by 1,000: 500 ÷ 1,000 = 0.5 litres.
In millilitres: 500 cc = 500 mL (no conversion needed).

This matches the default output of the converter above: 500 cc = 0.5 L = 500 mL.

CC vs mL: Are They the Same?

Yes. One cubic centimetre (1 cc or 1 cm³) is exactly equal to one millilitre (1 mL). The two units describe the same volume. The difference is context: "cc" is more common in medical settings (drug dosages, intravenous fluids, syringe volumes), while "mL" is preferred in food labelling, beverage manufacturing, and scientific writing. Both are accepted SI-compatible units.

Engine Displacement: CC to Litres

Car engines are described by their displacement, which is the total swept volume of all cylinders. Engine sizes are often given in cc in technical specifications but converted to litres for marketing. To convert engine displacement from cc to litres, divide by 1,000. A 1,998 cc engine is a 2.0-litre engine. A 2,494 cc engine rounds to a 2.5-litre engine. The litre figure is typically rounded to one decimal place.
