Ml to Cc

Volumetric Metrology & 1964 12th CGPM BIPM Resolution

In 1964, the 12th Conférence Générale des Poids et Mesures (CGPM) officially redefined the liter as a special name for one cubic decimeter. Consequently, 1 milliliter (mL) is mathematically identical to 1 cubic centimeter (cc or cm^3):

Primary Volumetric Equivalents

• 1 mL (Syringe): 1 cc = 0.001 L

• 5 mL (Pediatric Spoon): 5 cc = 1 Metric tsp

• 10 mL (Syringe): 10 cc = 0.338 fl oz

• 125 mL (Scooter): 125 cc = 0.125 L

• 250 mL (Dirt Bike): 250 cc = 0.250 L = 15.26 CID

• 600 mL (Sportbike): 600 cc = 0.600 L = 36.61 CID

• 1,000 mL (Liter Bike): 1,000 cc = 1.000 L = 61.02 CID

• 2,000 mL (Car Engine): 2,000 cc = 2.000 L = 122.05 CID

Equations

• Volume (cc) = Volume (mL) × 1.0

• Liters (L) = mL1,000

How to Use This Calculator

Enter your Volume Value to Convert (e.g. 250.0), Medical & Automotive Application Preset — choose from Custom Volume Value, 1 mL Insulin Syringe (1 cc), 5 mL Pediatric Spoon (5 cc), and Conversion Direction — choose from Milliliters to Cubic Centimeters (mL → cc / 1:1 exact), Cubic Centimeters to Milliliters (cc → mL / 1:1 exact).

The Formula

Conversion factors used in this calculator:

1 mL = 1 cc

Worked Example

A nurse administering a 5 cc liquid medication dose is giving exactly 5.0 mL (one standard metric medicinal teaspoon).

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.
