What is 1cc in MG?

The conversion between milliliters (mL) or cubic centimeters (cc) and milligrams (mg) is important in many fields, especially medicine and pharmacology. Knowing how to accurately convert between the two units allows for proper dosing and administration of medications and solutions. This article will provide a detailed explanation of how to convert 1cc to mg, along with examples and tips for remembering the conversion factor. We will also discuss the relationship between volume and mass and how density factors into the conversion. Read on to learn everything you need to know about converting 1cc to mg.

The Relationship Between Volume and Mass

Volume and mass are two separate but related physical properties. Volume refers to the three-dimensional space an object occupies and is measured in units such as milliliters (mL) or cubic centimeters (cc). Milligrams (mg) are a unit of mass, specifically a thousandth of a gram.

While these units describe different physical characteristics, there is a relationship between volume and mass that allows conversion between the two. This relationship is density. Density describes how tightly packed or concentrated matter is within a given volume. Substances with higher density have more mass in a given volume compared to substances with lower density.

Knowing the density of a substance allows us to convert between volume and mass units. For example, water has a density of 1 g/mL. This means that 1 mL of water has a mass of 1 gram. Using density as a conversion factor, we can convert volumes in mL to masses in grams. The same concept applies when converting cc to mg.

The Cubic Centimeter to Milligram Conversion Factor

To convert between cubic centimeters (cc) and milligrams (mg), we need to know the conversion factor that relates these two units. The conversion factor commonly used is:

1 cc = 1 mL = 1 gram (g)

And, we know:

1 g = 1000 mg


1 cc = 1000 mg

This tells us that 1 cc is equivalent to 1000 mg. The complete cubic centimeter to milligram conversion factor is:

1 cc = 1000 mg

Or, expressed as a fraction:

1 cc / 1000 mg

This conversion factor allows us to convert any cubic centimeter measurement to milligrams by multiplying by 1000. It also works in reverse, allowing conversion from mg to cc by dividing by 1000. Memorizing this simple conversion factor is key for quickly and easily converting between cc and mg.

Converting 1 cc to Milligrams

Now that we know the cubic centimeter to milligram conversion factor, converting 1 cc to mg is straightforward.

To convert 1 cc to mg, we simply multiply the 1 cc by the conversion factor:

1 cc x (1000 mg / 1 cc) = 1000 mg

Therefore, 1 cc is equivalent to 1000 mg.

Let’s look at some examples of using this conversion:

Example 1

Convert 5 cc to milligrams:

5 cc x (1000 mg / 1 cc) = 5000 mg

Example 2

Convert 0.5 cc to milligrams:

0.5 cc x (1000 mg / 1 cc) = 500 mg

Example 3

Convert 250 cc to milligrams:

250 cc x (1000 mg / 1 cc) = 250,000 mg

So in summary, to convert any cubic centimeter value to milligrams, we simply multiply the cc value by 1000. This quickly converts cc to the corresponding number of milligrams.

Converting Milligrams to Cubic Centimeters

We can also use the cubic centimeter to milligram conversion factor to convert in the opposite direction, from mg to cc.

To do this, we flip the conversion factor and divide instead of multiply:

1 cc / 1000 mg

Now let’s look at some examples converting milligrams to cc:

Example 1

Convert 5000 mg to cc:

5000 mg x (1 cc / 1000 mg) = 5 cc

Example 2

Convert 500 mg to cc:

500 mg x (1 cc / 1000 mg) = 0.5 cc

Example 3

Convert 250,000 mg to cc:

250,000 mg x (1 cc / 1000 mg) = 250 cc

So in summary, to convert milligrams to cubic centimeters, divide the mg value by 1000. This provides the volume in cc.

Tips for Remembering the 1 cc to mg Conversion

When first learning how to convert between cc and mg, it can be difficult to remember the exact conversion factor. Here are some tips to help you remember that 1 cc = 1000 mg:

– Think about the prefix milli- – milli means one thousandth. So 1 cc = 1000 mg.

– Remember that a cc is the same as 1 mL and 1 mL of water = 1 gram. Since 1 g = 1000 mg, 1 cc must equal 1000 mg.

– Visualize a 1 cc syringe – if you fill it with water, the mass of that water would be 1 g or 1000 mg.

– Use mnemonics or memory devices like “1cc, 1ML, 1000mg” or “CCMgram”.

– Do practice conversions between cc and mg until the conversion factor is committed to memory.

With practice and use, converting between 1 cc and 1000 mg will become second nature. Having a solid understanding of the relationship between volume and mass units will help this conversion stick.

Applications of Converting Between cc and mg

Being able to interconvert cubic centimeter and milligram units is extremely useful for many scientific and medical applications. Here are some examples:


– Dosing medications and drugs – many medication doses are prescribed in mg but solutions come packaged in cc. Converting between the units is essential for administering correct doses.

Nutritional Sciences

– Measuring food or nutrient intake – some nutritional recommendations are given in cc or mg, requiring conversion between the units.


– Preparing solutions – chemicals or reagents may be measured in mass (mg) but solvents are generally dispensed in volume (cc). Converting between cc and mg is necessary when following recipes.

Laboratory Research

– Quantifying chemicals, compounds, or biological samples – research procedures may require measuring out substances in mg but using pipettes or syringes that are calibrated in cc.

Medical Procedures

– Administering injections or IV fluids – dosage directions are usually in mg but most syringes measure in cc. Converting between units ensures proper dosing.

Being proficient at converting 1 cc to 1000 mg, and vice versa, is clearly valuable across many technical fields. Mastering this conversion factor unlocks a breadth of real-world applications.

Common Conversion Mistakes

When first learning to convert between cubic centimeters and milligrams, there are a few common mistakes to avoid:

– Forgetting that 1 cc = 1000 mg, not 100 mg or 1 mg. Keep practicing the conversion factor to commit it to memory.

– Flipping the conversion factor upside down. Double check that cc is on top and mg is on bottom before calculating.

– Mistaking mass and volume units. Be clear on the definitions of mg as a mass unit and cc as a volume unit.

– Trying to convert without a density conversion factor. Recall that density links mass and volume.

– Canceling units incorrectly. Don’t cancel cc and mg units – these are not the same unit. Only cancel identical units in the numerator and denominator.

– Rounding too soon. Carry extra significant figures through the entire calculation, only rounding the final result.

With vigilance and practice, these common mistakes can be overcome. Having awareness of potential pitfalls will help you successfully master cc to mg conversions.


In summary, the key points to remember when converting 1 cc to mg are:

– 1 cc is equivalent to 1 mL volume

– The density of water can be used to relate 1 cc to 1 g

– Since 1 g = 1000 mg, 1 cc = 1000 mg

– To convert cc to mg, multiply by 1000

– To convert mg to cc, divide by 1000

– Practice makes perfect – work example problems until the conversion is memorized

– Be aware of common mistakes like forgetting the factor or flipping units

Having a solid understanding of volume, mass and density allows you to intuitively convert between cubic centimeters and milligrams. Mastering this important conversion factor unlocks a wide range of applications across science, medicine and pharmacy. With practice, converting 1 cc to 1000 mg will become second nature.
