Formula and methodology
Formula: Volume = length × width × height; mass = density × volume; weight = mass × gravity; specific weight = density × gravity.
This page keeps geometric size, material density, mass, and force separate. It uses a uniform rectangular solid and a supplied gravitational acceleration so the same arithmetic can be used for a classroom example or a documented planning scenario.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Length — m; minimum 1.0E-6; maximum 1000000
- Width — m; minimum 1.0E-6; maximum 1000000
- Height — m; minimum 1.0E-6; maximum 1000000
- Mass density — kg/m³; minimum 1.0E-6; maximum 1000000000
- Gravitational acceleration — m/s²; minimum 1.0E-6; maximum 10000
Worked example
| Input | Value |
|---|---|
| Length | 2 |
| Width | 0.5 |
| Height | 0.25 |
| Mass density | 7850 |
| Gravitational acceleration | 9.80665 |
Volume = 0.25 m³; mass = 1,962.5 kg; weight ≈ 19,245.55 N.
Assumptions and limits
- All three dimensions use metres and form a rectangular cuboid.
- Density is uniform and entered in kilograms per cubic metre.
- The gravity value is a selected modeling assumption, not a local measurement fetched by the page.
- Mass means amount of matter; gravitational weight is the force m×g in newtons.
- Hollows, voids, coatings, fasteners, moisture, buoyancy, and tolerances are not modeled.
- The result is not a structural capacity, lifting plan, shipping certification, or safety approval.
