Example: https://askcalculators.com/calculator/mass-calculator/?density=2.7&volume=100

## Inputs
- density: Density (g/cm³); type=number; optional; default=2.7
- volume: Volume (cm³); type=number; optional; default=100

## Outputs
- result: Result; format=text; primary

## Formula
Mass = density × volume, with unit conversions applied before and after the calculation.

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
