Is 1 mL the same as 1cc?

Quick Answer

Yes, 1 mL is the same as 1 cc. mL and cc are two different abbreviations that both stand for the metric unit “milliliter”. 1 milliliter is equal to 1 cubic centimeter. So 1 mL = 1 cc.

What is a Milliliter?

A milliliter (mL) is a unit of volume in the metric system. It is equal to 1/1000 of a liter.

The milliliter is used to measure small volumes of liquids and gases. For example, medications are often measured in milliliters.

The milliliter is one of the most commonly used units in the metric system, along with the liter, gram, and meter.

Milliliter Abbreviations

The milliliter can be abbreviated in a few different ways:

– mL
– ml
– ML

mL is the most common abbreviation used today.

What is a Cubic Centimeter?

A cubic centimeter (cc or cm3) is another unit of volume derived from the metric system.

A cubic centimeter represents the volume of a cube that measures 1 centimeter on each side. Since a centimeter is 1/100 of a meter, a cubic centimeter is equal to:

(1/100 m) x (1/100 m) x (1/100 m) = 1/1,000,000 m3

This simplifies to:

1 cc = 1 cm3 = 1 mL

So a cubic centimeter is exactly equal to 1 milliliter. The cc abbreviation is an older term that stands for cubic centimeter.

Cubic Centimeter Abbreviations

The cubic centimeter can be abbreviated in a few ways:

– cc
– cm3
– CC

While cc is still sometimes used today, mL has become the standard abbreviation for milliliters and cubic centimeters.

Milliliter and Cubic Centimeter Equivalents

Since 1 mL is the same as 1 cc, you can use the units interchangeably. For example:

– 5 mL = 5 cc
– 0.5 mL = 0.5 cc
– 10 mL = 10 cc

This works for any volume. Some other equivalent measurements include:

Milliliters Cubic Centimeters
1 mL 1 cc
5 mL 5 cc
100 mL 100 cc
250 mL 250 cc

As you can see, the milliliter and cubic centimeter values are identical for any given volume.

Milliliter and Cubic Centimeter Relationships

To summarize:

– 1 cc = 1 cm3
– 1 cm3 = 1 mL
– 1 mL = 1 cc

So cubic centimeter, milliliter, and cc all refer to the same volume measurement. They can be used interchangeably.

Milliliter and Cubic Centimeter Uses

Both milliliters and cubic centimeters are very commonly used for measuring volumes in science, medicine, and cooking.

Some examples include:

– Measuring liquid medications or injectable drugs. Many prescriptions will specify the dosage in mL or cc.
– Measuring out ingredients for recipes. For small amounts of liquids like milk or water, mL or cc are convenient units.
– Titrating solutions in a chemistry lab. Using milliliters allows for precise measurements during experiments.
– Measuring blood draws. Phlebotomists will often draw blood in cubic centimeters for testing.
– Calculating gas density. The density of gases can be determined using volumes in mL or cc.
– Calibrating pipettes in a biology lab. Micropipettes can measure very small liquid volumes in milliliters.

So in many scientific and medical settings, the milliliter (mL) and cubic centimeter (cc) are standard units to quantify liquids and gases. They are often used interchangeably due to being equal volumes.

Advantages of Milliliters and Cubic Centimeters

There are a few key advantages to using milliliters and cubic centimeters as volume units:

– **Precise** – They allow for measurement of very small volumes, down to decimal places if needed. A unit like teaspoons would not be as precise.

– **Metric volume** – They are metric units, which aligns with the other SI metric measurements. This allows for easy conversions and calculations.

– **Water equivalence** – One mL of water occupies one cc. So water volumes can be easily measured.

– **Lab equipment** – Most laboratory glassware, like beakers, flasks, and pipettes, are calibrated in milliliters and cubic centimeters.

So in many scientific applications, milliliters or cubic centimeters are the preferred units for their precision and alignment with other SI units.

Converting Between Milliliters and Other Units

Since milliliters are metric units, they can easily be converted to and from other metric volume units:

– 1 liter (L) = 1000 milliliters
– 1 milliliter = 0.001 liter

Some common milliliter conversions include:

From To Conversion
1 mL 0.001 L 1 mL = 0.001 L
250 mL 0.25 L 250 mL = 0.25 L
500 mL 0.5 L 500 mL = 0.5 L
750 mL 0.75 L 750 mL = 0.75 L
1 L 1000 mL 1 L = 1000 mL

Conversions to and from other metric units like grams and meters can also be done, using the density or volume formulas. Since the milliliter is equivalent to the cubic centimeter, the same conversions apply when converting cc to other metric units.

Milliliters to Ounces Conversion

Milliliters can also be converted to fluid ounces, for those more familiar with the imperial fluid ounce unit:

– 1 milliliter = 0.0338 fluid ounces
– 1 fluid ounce = 29.5735 milliliters

Some common conversions include:

Milliliters Fluid Ounces Conversion
1 mL 0.0338 fl oz 1 mL = 0.0338 fl oz
15 mL 0.5 fl oz 15 mL = 0.5 fl oz
30 mL 1 fl oz 30 mL = 1 fl oz
240 mL 8 fl oz 240 mL = 8 fl oz = 1 cup
480 mL 16 fl oz 480 mL = 16 fl oz = 1 pint

So while milliliters and cubic centimeters are part of the metric system, they can be converted as needed to imperial fluid measurements like fluid ounces and cups.

Milliliter and Cubic Centimeter Usage Tips

When using milliliters or cubic centimeters as a volume measurement, keep these tips in mind:

– Use mL and cc interchangeably – they are equal units.

– Make sure your lab equipment can measure in milliliters. Graduated cylinders, pipettes, burettes, and other glassware should have mL markings.

– Use milliliters to measure very small liquid volumes precisely. Larger volumes may be better measured in liters.

– When converting between units, double check your conversion factors to avoid errors.

– For consumer products, milliliter volumes may be accompanied by fluid ounces. Check for both mL and fl oz markings.

– Water volumes can be assumed to be equal in mL and cc. 1 mL of water occupies 1 cc.

– When writing medically, opt for mL over cc to avoid confusion. mL has become the standard abbreviation.

By understanding that 1 mL = 1 cc, and how to properly use and convert milliliter measurements, you can utilize them effectively in science and medicine.


In summary, 1 milliliter (mL) is equivalent to 1 cubic centimeter (cc). They are two different terms for the same metric volume measurement.

Milliliters and cubic centimeters can be used interchangeably to quantify volumes, especially in scientific fields. Their key advantages are being precise metric units that align with other SI units and measurement tools.

While the abbreviations differ, mL and cc values represent the same volume for any given measurement. When writing medically, mL is now the standard abbreviation, though cc may still occasionally be seen.

Understanding the relationship between milliliters and cubic centimeters allows you to utilize them effectively as units of volume.
