📖 About Oz to Cc

Volumetric Metrology & 1964 12th CGPM BIPM Standards

A cubic centimeter ( extcm^3 or cc) is identically equal to 1 milliliter (mL) by international BIPM decree since 1964:

  • 1 cc: 1 cm^3 1.000000 mL = 0.001000 L = 0.061024 cu in = 0.033814 US fl oz
  • 1 US Fluid Ounce (fl oz): 29.573530 cc = 29.573530 mL = 1.804687 cu in
  • 1 UK Imperial Fluid Ounce: 28.413063 cc

Primary Engine & Clinical Volume Benchmarks

  • 30 cc Syringe: = 1.014 fl oz = 2.03 Tbsp
  • 60 cc Feeding Syringe: = 2.029 fl oz = 4.06 Tbsp
  • 125 cc Scooter: = 4.227 fl oz = 7.63 cu in
  • 250 cc Dirt Bike: = 8.454 fl oz = 15.26 cu in
  • 500 cc Motorcycle: = 16.907 fl oz = 30.51 cu in
  • 600 cc Supersport: = 20.288 fl oz = 36.61 cu in
  • 1,000 cc (1.0L Engine): = 33.814 fl oz = 61.02 cu in

Equations

  • Cubic Centimeters (cc) = Fluid Ounces (fl oz) × 29.57353
  • Fluid Ounces (fl oz) = Cubic Centimeters (cc)29.57353

How to Use This Calculator

Enter your Volume Value to Convert (e.g. 8.45), Fluid Ounce Standard — choose from US Customary Fluid Ounce (29.574 cc / Standard US), UK Imperial Fluid Ounce (28.413 cc / British Pint), US Nutrition / FDA Labeling Ounce (30.000 cc), Clinical & Engine Benchmark — choose from Custom Volume Value, 1.00 fl oz (29.57 cc / 30 cc Dosing Syringe), 2.03 fl oz (60.00 cc / 60 cc Oral Syringe), and Conversion Direction — choose from Fluid Ounces to Cubic Centimeters (fl oz → cc / multiply by 29.574), Cubic Centimeters to Fluid Ounces (cc → fl oz / divide by 29.574). Results update instantly as you type — adjust any value to compare scenarios.

Worked Example

A 250cc dirt bike engine displacement equals exactly 8.45 US fluid ounces (or 15.26 cubic inches).

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.
