CC to ML Converter
Convert cc to mL and back instantly. Since 1 cc = 1 mL exactly, this is the simplest metric conversion. Perfect for medical syringes, lab work, and recipes.
Is 1 cc equal to 1 mL?
Yes, 1 cc (cubic centimeter) is exactly equal to 1 mL (milliliter). They are identical volumes expressed in different units. CC is derived from the cubic measurement system (1 cm × 1 cm × 1 cm), while mL is derived from the liter system (1/1000 of a liter). In medical contexts, syringes are typically marked in cc (e.g., 3 cc, 5 cc), while IV bags and medication bottles are marked in mL. In cooking, measuring cups use mL. The interchangeability means 250 cc = 250 mL, 500 cc = 500 mL, and so on.
Why do medical syringes use cc instead of mL?
Medical syringes historically use cc because they are designed based on cubic measurements. The barrel of a syringe is essentially a calibrated cylinder, and cc represents the actual physical space (cubic centimeters). While both units are identical, cc is the traditional medical standard. Key medical conversions: Insulin syringes: marked in units (100 units = 1 cc = 1 mL). Standard syringes: 1 cc, 3 cc, 5 cc, 10 cc sizes. IV fluids: 500 cc bag = 500 mL = 0.5 L. Dosage calculations: 1 mg/mL = 1 mg/cc for water-based solutions.
How do I convert cc to mL?
Since cc and mL are equivalent units, the conversion is 1:1. Formula: mL = cc (same number). CC to mL: the number stays the same. mL to CC: the number stays the same. Examples: 5 cc = 5 mL. 50 cc = 50 mL. 250 cc = 250 mL. 1000 cc = 1000 mL = 1 L. 0.5 cc = 0.5 mL. This 1:1 relationship makes it the simplest conversion in the metric system. For larger volumes: 1000 cc = 1000 mL = 1 liter. For smaller: 0.1 cc = 0.1 mL. Always use the same number.
When should I use cc versus mL?
Use cc (cubic centimeters) when: Measuring engine displacement (250 cc motorcycle, 2000 cc car). Medical syringes and injections. Laboratory cylinders and beakers marked in cc. Automotive coolant and hydraulic fluid capacities. Use mL (milliliters) when: Cooking and recipes (250 mL milk). Beverage packaging (500 mL water, 355 mL soda). Medication dosages (5 mL cough syrup). IV fluid bags (1000 mL). Scientific measurements in most modern labs. Convert freely between them since they are identical: 1 cc = 1 mL always.
