Density Calculator accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

The formula triangle is: * **Density ($ρ$)** = Mass ($m$) / Volume ($V$) * **Mass ($m$)** = Density ($ρ$) × Volume ($V$) * **Volume ($V$)** = Mass ($m$) / Density ($ρ$)

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

Solve For: Density (ρ)
Value 1: 10
Value 2: 2

Expected outputs

Calculated Value: 5

Known limitations

This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

Mass, density, and volume are entered in compatible units.
Volume and density must be greater than zero when they appear in the denominator.
The calculation assumes a uniform material or average density for the sample.

Unit handling

Solve For accepts one of the configured options.
Value 1 accepts numeric values.
Value 2 accepts numeric values.

Rounding rules

Number displays use up to 2 decimal places in the calculator UI.
