How to use this calculator
- Select density, mass, or volume as the unknown.
- Enter the two known positive values.
- Select the unit for each value and calculate.
Formula and variables
rho = m / V
| Symbol | Meaning | Unit |
|---|---|---|
| rho | density | mass/volume |
| m | mass | mass |
| V | volume | volume |
Worked example
997 g occupying 1 L has density 0.997 g/mL.
Interpretation
Density is mass per volume; all values are normalized to compatible canonical dimensions before solving.
Common mistakes
- Use the volume occupied by the sample.
- Do not enter zero or negative physical quantities.
Frequently asked questions
What is the density formula?
Density equals mass divided by volume.
Can the calculator solve for mass or volume?
Yes. Select the required unknown and enter the other two values.
Is specific gravity the same as density?
No. Specific gravity is a dimensionless ratio to a reference density.
Can I use scientific notation?
Yes. Enter values such as 6.022e23 or 1.0e-6 in a numeric field.
How should I round the result?
Keep extra digits during the calculation. Round the final result to the precision required by your data.
