| Case | Material | Volume | Density | Mass (computed) |
|---|---|---|---|---|
| 1 | Water | 2.0 L | 998.2 kg/m³ | ≈ 1.996 kg |
| 2 | Aluminum | 1500 cm³ | 2700 kg/m³ | ≈ 4.050 kg |
| 3 | Steel | 0.75 ft³ | 7850 kg/m³ | ≈ 166.7 lb |
| 4 | Custom | 1.5 gal | 0.92 g/mL | ≈ 5.224 kg |
m = ρ × V
This calculator converts your chosen volume and density units into SI, multiplies them to get mass in kilograms, then converts the mass to grams, pounds, and ounces for easy comparison.
Mass depends directly on density, so selecting the right value matters more than unit choice. Water is near 998 kg/m³ at room temperature, while metals range from about 2,700 kg/m³ for aluminum to around 7,850 kg/m³ for steel.
Liquids expand with heat, lowering density and reducing mass for the same geometric volume. For example, water density drops as temperature rises, which can shift lab results. Gases are more sensitive; density changes with pressure and temperature, so match conditions to your density source.
Volume units like liters, cubic centimeters, and gallons are converted internally to cubic meters. Density units like g/cm³ and lb/ft³ are converted to kg/m³. Using one SI pathway avoids hidden rounding and keeps results consistent when you switch units.
The calculator reports kilograms, grams, pounds, and ounces to support engineering notes, purchasing, and experiments. Small volumes with high densities may look tiny in kilograms but meaningful in grams. Large container volumes may be easier to interpret in pounds. Precision settings help present clean numbers without overstating certainty.
For solutions, slurries, and composites, density can vary by concentration and trapped air. If your material contains voids, use bulk density rather than true material density. For aggregates and powders, bulk density can change with packing, moisture, and particle size distribution, so measure a representative sample whenever accuracy is critical.
Uncertainty typically comes from volume measurement and density selection. A 2% error in volume and a 3% error in density combine to a noticeable mass uncertainty. Use calibrated glassware for liquids and reliable geometry for solids. For safety margins, calculate with upper and lower density bounds.
Common uses include estimating reagent mass from a measured volume, sizing loads for storage tanks, predicting shipping weight for fluids, and checking material usage in casting or molding. In quality control, comparing expected mass to measured mass can reveal wrong material, contamination, or incorrect fill level quickly.
CSV export is ideal for spreadsheets, batch calculations, and lab notebooks, while PDF export supports quick sharing and archiving. Keep exports with the density source and measurement conditions so others can reproduce the calculation. Documenting units and assumptions makes the result defensible.
It uses m = ρ × V. Your inputs are converted into SI units, multiplied to get mass in kilograms, then converted to grams, pounds, and ounces for display.
The physical density stays the same, but the number you type must match the unit you selected. If the unit changes, re-enter the density value in that unit or use a preset material.
No. Presets are representative values near room conditions. Real density varies with composition, temperature, and manufacturing. For precise work, measure density or use a certified datasheet value.
Use the mixture’s effective density, not the density of a pure component. For solutions, density depends on concentration and temperature. If unsure, measure density using a known volume and mass.
Choose the unit that matches your measurement tool. Laboratory glassware often reads milliliters or liters, while engineering drawings may use cubic meters or cubic centimeters. Conversions are handled automatically.
Bulk density includes voids and air gaps in powders, grains, and porous materials. Use it when you care about mass per container volume, such as packaging, storage, and handling calculations.
Precision controls rounding of displayed numbers. It helps present neat outputs while avoiding false certainty. Set it to match the quality of your measurements and the reliability of your density value.
Accurate conversions help experiments, designs, and quality control daily.
