Set the calculation object first, then calculate

Calculate among density, mass, and volume. Choose common materials, units, and result precision. Batch CSV is parsed locally, previews the first 20 rows, and processes all files and data.

ρ = m / V Multi-unit conversion CSV Batch

Single calculation

Choose the parameter to calculate and fill in the other two known values. To use a reference material, select it first to auto-fill density.

Calculation settings Set up first, then calculate

Calculation target

Common materials

Selecting one auto-fills density. You can still edit it manually.

Result precision

Mass m

Volume V

Density ρ

Tip: Select the target and units first, then enter values to calculate.

Batch calculation

CSV headers can use name,mass,mass_unit,volume,volume_unit,density,density_unit,mode. Enter at least two parameters per row. mode can be blank for auto-detect.

Import data Supports multiple CSV files

When uploading multiple CSVs, only the first 20 files are listed. All files will be processed. Output names match the originals; duplicates get numbers automatically.

Instructions

Software Usage Instructions

Select the calculation method: Switch between “Single Calculation” and “Batch Calculation.” Single Calculation is suitable for quick conversions, while Batch Calculation is suitable for processing CSV spreadsheet data.
Set the calculation target: In Single Calculation, choose “Calculate Density,” “Calculate Mass,” or “Calculate Volume.” The tool will automatically hide the parameter to be calculated and only keep the known parameters that need to be entered.
Enter parameters and units: Enter values for mass, volume, or density, and select the corresponding unit for each parameter. Common units such as kg, g, m3, cm3, L, mL, kg/m3, and g/cm3 are supported.
Use material references: You can select common materials such as water, air, aluminum, iron, copper, concrete, and glass. The tool will automatically fill in the reference density, which users can still modify as needed.
Set result precision: Choose 2, 4, 6, or 8 decimal places according to the calculation scenario, then click “Start Calculation” to view the result and common unit conversions.
Save common settings: Click “Save Settings” to record the calculation target, units, and precision; the next time you use the tool, you can click “Load Saved Settings.”
Batch calculate CSV: CSV headers can use name,mode,mass,mass_unit,volume,volume_unit,density,density_unit. Each row must include at least two parameters, and mode can be density, mass, volume, or auto.
Export results: After batch calculation is complete, the interface previews the first 20 rows of results. Click “Download All Results ZIP” to get the processed CSV file.

FAQ

A: The density formula is ρ = m / V, where ρ represents density, m represents mass, and V represents volume. From this, m = ρ × V and V = m / ρ can be derived.

A: 1 g/cm3 = 1000 kg/m3. For example, the density of water is about 1 g/cm3, which can also be written as 1000 kg/m3.

A: Material density can be affected by temperature, moisture content, purity, alloy composition, and porosity. The material densities in the tool are suitable as reference values. For engineering calculations, it is recommended to refer to the material datasheet or test data.

A: We recommend using the columns name, mode, mass, mass_unit, volume, volume_unit, density, and density_unit. Each row must include at least two of the three parameters: mass, volume, and density. mode can be left blank or set to auto.

A: Failed rows are usually caused by empty values, unsupported unit formats, insufficient parameters, or values less than or equal to 0. The exported results CSV retains the error column, so you can modify the original data according to the提示 and recalculate.

A: Result files will use the original CSV file names as much as possible. If duplicate names occur, the tool will add numbers to the file names to distinguish them and package all results into a ZIP download.
