Mass vs Volume
To begin with, it’s important to know what mass and volume are.
Mass is the amount of matter in an object, measured in units like grams or kilograms.
Volume, on the other hand, is the amount of space an object occupies, typically measured in litres or cubic meters.
The Role of Density
So, how do we convert mass to volume? The answer lies in a property known as density, which is the mass of a substance per unit volume. It’s usually expressed in terms like kilograms per cubic meter or grams per cubic centimeter.
So, if we know the density of a substance, we can use it to convert mass to volume. The formula is simple: Volume = Mass / Density
How to do I find the density of a material?
Density values for common substances can be found online or in reference books. If you have purchased the material from a supplier, they may also provide you with the density value.
If you’re working with an uncommon substance, you may need to measure its density yourself using specialized tools.
Another option is to use our free grams to ml converter, which includes built-in density values for common crafting ingredients like oils, waxes, and butters — so you can skip the lookup step entirely.
How do I convert a mass to volume measurement?
Let’s take water as an example.
The density of water is 1 gram per cubic centimeter (g/cm³). So, if we have 2000 grams (or 2 kilograms) of water, the volume would be:
Volume = 2000 g / 1 g/cm³ = 2000 cm³
Remember, one cubic centimeter is equivalent to one millilitre, so 2000 cm³ is equal to 2000 ml or 2 litres.
Converting Mass to Volume in Soapmaking
Consider a soapmaking scenario.
A common ingredient in soapmaking is coconut oil, which has a density of approximately 0.92 g/cm³. If our soap recipe calls for 500 grams of coconut oil, we can calculate the volume of coconut oil needed using the formula:
Volume = Mass / Density
Applying the formula, we get:
Volume = 500 g / 0.92 g/cm³ ≈ 543.48 cm³
Now, since 1 cm³ is equivalent to 1 ml, we can say that 543.48 cm³ of coconut oil is needed, or roughly 543.48 milliliters. This conversion allows soapmakers to accurately measure out their ingredients, ensuring a consistent and high-quality end product.

Frequently Asked Questions
What is the formula for converting mass to volume?
The formula for converting mass to volume is: Volume = Mass ÷ Density. To use it, you need to know both the mass of your substance (in grams or kilograms) and its density (in g/cm³ or g/mL). For example, 500g of coconut oil with a density of 0.92 g/cm³ gives a volume of 500 ÷ 0.92 = approximately 543 mL. One cubic centimetre equals one millilitre, so the result is directly in mL.
How do I convert grams to millilitres for crafting recipes?
To convert grams to millilitres, divide the mass in grams by the ingredient's density in g/mL. Water has a density of 1 g/mL, so 200g of water = 200 mL exactly. Oils and waxes have lower densities — coconut oil is about 0.92 g/mL, so 200g of coconut oil = approximately 217 mL. For crafting ingredients with known densities, our free grams to mL converter handles the calculation automatically without needing to look up density values.
Why does mass-to-volume conversion matter for recipe costing?
Mass-to-volume conversion matters for recipe costing because ingredients are often purchased by weight (grams or kg) but recipes may call for measurements by volume (mL or cups). If you don't convert accurately, your material cost calculations will be wrong — you may undercount how much of a material you used per batch, leading to underpriced products. Craftybase lets you enter materials in any unit and handles the conversion automatically when calculating your cost of goods sold.
How do I find the density of a crafting ingredient?
The easiest way to find the density of a crafting ingredient is to check your supplier's product data sheet, which often lists density or specific gravity. For common ingredients, reference values are widely available online — for example, sweet almond oil is approximately 0.91 g/mL and shea butter is around 0.96 g/mL. Alternatively, use our free grams to mL converter, which has pre-loaded density values for popular soap, candle, and cosmetic ingredients.
Is 1 gram equal to 1 millilitre?
1 gram equals 1 millilitre only for water, because water has a density of exactly 1 g/mL at room temperature. For every other substance, the conversion depends on that substance's density. Oils, waxes, butters, and alcohols all have densities below 1 g/mL, meaning 1 gram of those materials takes up more than 1 mL of volume. Always check the density of the specific ingredient before assuming a 1:1 gram-to-mL relationship.
Conclusion
In conclusion, converting from mass to volume is a simple process provided we know the density of the substance in question. This basic principle is a vital tool in fields as varied as cooking, soapmaking, candlemaking, and chemistry. So next time you find yourself needing to convert from mass to volume, simply recall the role of density and you’ll be well equipped to handle the task!
