80 mg is approximately 0.08 ml when converted assuming the density is 1 mg/ml.
This conversion assumes the substance density is equal to water, meaning 1 mg equals 0.001 ml. Since mg measures mass and ml measures volume, the conversion depends on density, but for water or similar liquids, the calculation is straightforward.

Conversion Formula
To convert milligrams (mg) to milliliters (ml), you need to know the substance density in mg/ml. When the density is 1 mg/ml, the formula is:
Volume (ml) = Mass (mg) ÷ Density (mg/ml)
The formula works because mg measures mass while ml measures volume. Density connects mass and volume, so dividing mass by density gives volume. For water, density is 1 mg/ml, so 80 mg ÷ 1000 equals 0.08 ml.
Example:
- Mass = 80 mg
- Density = 1000 mg/ml (since 1 g/ml = 1000 mg/ml)
- Volume = 80 mg ÷ 1000 = 0.08 ml
Conversion Example
- Convert 120 mg to ml:
- Step 1: Identify density (assumed 1000 mg/ml)
- Step 2: Divide mass by density: 120 ÷ 1000
- Step 3: Result = 0.12 ml
- Convert 250 mg to ml:
- Step 1: Use density 1000 mg/ml
- Step 2: 250 ÷ 1000 = 0.25
- Step 3: Volume is 0.25 ml
- Convert 500 mg to ml:
- Step 1: Density 1000 mg/ml
- Step 2: 500 ÷ 1000 = 0.5
- Step 3: Volume equals 0.5 ml
- Convert 75 mg to ml:
- Step 1: Density 1000 mg/ml
- Step 2: 75 ÷ 1000 = 0.075
- Step 3: Result is 0.075 ml

Conversion Definitions
mg (Milligram): A milligram is a unit of mass equal to one-thousandth of a gram. It is used to measure very small quantities of substances, especially in fields like medicine and chemistry, where precise mass measurement is necessary for dosage or reactions.
ml (Milliliter): A milliliter is a unit of volume equal to one-thousandth of a liter. It’s commonly used to measure liquids and small volumes, such as in cooking, medicine, and science. One milliliter is the same volume as one cubic centimeter.
Conversion FAQs
Why can’t I convert mg to ml without knowing the substance density?
Milligrams measure mass, while milliliters measure volume. Without knowing the density, which links mass to volume, a direct conversion isn’t possible. Different substances have different densities, so the same mass can occupy different volumes.
Is the conversion of 80 mg to 0.08 ml valid for all substances?
No, this conversion assumes a density of 1 mg/ml, like water. Other substances with higher or lower densities will have different volume values for the same mass.
How can I find the density if it’s not given?
Density can be found on product datasheets, scientific literature, or by measuring mass and volume experimentally. Without this, conversions between mg and ml remain estimates.
Does temperature affect the conversion between mg and ml?
Yes, temperature changes can alter the density of liquids, which affects the volume for a given mass. For precise conversions, temperature should be considered.
Can I use the conversion tool for solids?
The tool is designed for liquid substances where density is close to water. For solids, volume depends on shape and packing, so mg to ml conversion may not apply directly.
