How to Convert Volume to Mass Step by Step

Follow these four simple steps to convert any volume to mass.

1

Measure Volume

Determine the volume of your substance in milliliters (mL). Use a graduated cylinder, measuring cup, or syringe for accurate measurements.

2

Find Density

Look up the density of your substance in g/mL. Water is 1.0 g/mL, honey is 1.42 g/mL, and olive oil is 0.918 g/mL. Use the density table below for common substances.

3

Apply Formula

Multiply volume by density: Mass (g) = Volume (mL) ร— Density (g/mL). For example, 100 mL of honey: 100 ร— 1.42 = 142 grams.

4

Convert Units

Convert to your desired unit: multiply grams by 1,000 for mg, divide by 1,000 for kg, or divide by 453.592 for pounds. Example: 142 g = 142,000 mg = 0.142 kg.

How to Convert Volume to Mass

Volume-to-mass conversion requires knowing the density of the substance. Density tells you how much mass is packed into each unit of volume.

The Formula

Mass (mg) = Volume (mL) ร— Density (g/mL) ร— 1000

Step-by-Step Example

Converting 250 mL of honey to milligrams:

  1. Identify the density of honey: 1.420 g/mL
  2. Multiply: 250 ร— 1.420 = 355 grams
  3. Convert to mg: 355 ร— 1000 = 355,000 mg

So 250 mL of honey = 355,000 mg.

To go the other way, use the mass to volume converter. For specific units, the milliliters to milligrams tool and the mL to grams converter apply the same formula. Since density drives every result, you can compute it with the density calculator, or return to the main mL to mg converter for more options.

Volume to Mass FAQ

Common questions about converting volume to mass.

Multiply the volume in mL by the substance's density (in g/mL), then multiply by 1,000 to get milligrams. The formula is: mg = mL ร— density ร— 1000. For example, 50 mL of water (density 1.0) = 50 ร— 1.0 ร— 1000 = 50,000 mg.

Because every substance has a unique density. Density measures how tightly mass is packed into a given volume. Honey (density 1.42 g/mL) has more mass per milliliter than water (1.0 g/mL), so 100 mL of honey weighs 42% more than 100 mL of water.

Only for pure water at 4 ยฐC. For all other substances, the relationship depends on density. 1 mL of olive oil weighs about 0.918 g, while 1 mL of mercury weighs a massive 13.534 g. Always use the correct density for your substance.

No. Volume and mass are fundamentally different physical quantities. Without density โ€” which bridges the two โ€” there is no way to calculate one from the other. If you don't know the density, you can look it up in reference tables, or use our substance selector above for instant results.

From a volume in milliliters you can convert to milligrams (mg), grams (g), kilograms (kg), or pounds (lb). All require density. Simply multiply mL ร— density to get grams, then scale to your desired unit (รท1000 for kg, ร—1000 for mg, รท453.592 for lb).
