Understanding cc and Fluid Ounces
Converting between cubic centimeters (cc) and fluid ounces bridges the gap between metric volume measurements and the US/Imperial systems. Since 1 cc = 1 mL, this conversion is the same as converting mL to fluid ounces.
What Is a Cubic Centimeter?
A cubic centimeter (cc or cm³) is a metric unit of volume equal to the volume of a cube measuring 1 cm on each side. By definition, 1 cc equals exactly 1 milliliter (mL). This unit is commonly used in medicine (syringes), science, and for measuring engine displacement.
US vs Imperial Fluid Ounces
There are two types of fluid ounces in common use:
- US fluid ounce: 29.5735 mL — used in the United States
- Imperial fluid ounce: 28.4131 mL — used in the UK and some Commonwealth countries
The Imperial fluid ounce is slightly smaller than the US fluid ounce, meaning you get more Imperial fl oz from the same volume of liquid.
Common Conversions
Here are some useful relationships:
- 1 US fl oz ≈ 29.57 cc (or mL)
- 30 cc ≈ 1.01 US fl oz (approximately 1 fl oz)
- 1 Imperial fl oz ≈ 28.41 cc (or mL)
- A standard shot glass is about 44 cc (1.5 US fl oz)

Frequently Asked Questions
1 US fluid ounce equals 29.57 cc (or mL). 1 Imperial fluid ounce equals 28.41 cc. Since 1 cc = 1 mL exactly, these are also the mL values.
Divide the cc value by 29.5735 to get US fluid ounces, or by 28.4131 to get Imperial fluid ounces. For example: 60 cc ÷ 29.5735 ≈ 2.03 US fl oz.
Yes! 1 cc = 1 mL exactly by definition. Converting 30 cc to ounces gives the same result as converting 30 mL to ounces.
A US fluid ounce is 29.57 mL, while an Imperial fluid ounce is 28.41 mL. The Imperial fl oz is about 4% smaller. This means 1 liter = 33.81 US fl oz but 35.20 Imperial fl oz.
A standard US shot glass is 1.5 US fluid ounces, which equals about 44 cc (or mL). Shot glass sizes vary by country: UK shots are typically 25 or 50 mL.
Use the same formula. A 600 cc engine has a displacement of 600 mL, which equals about 20.29 US fl oz. However, engine size is typically expressed in cc or liters rather than ounces.
