Weight Converter 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

Conversions use standard international factors based on the gram: * **1 Pound (lb)** = 453.59237 grams * **1 Kilogram (kg)** = 1000 grams * **1 Ounce (oz)** = 28.3495 grams

Test cases

Default input regression check

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

Inputs

Weight: 1
From Unit: Kilogram (kg)
To Unit: Pound (lb)

Expected outputs

Converted Value: 2.2
Logic: Multiply by 2.205

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

The calculator applies standard mass-conversion constants and does not adjust for gravity or local weighing conditions.
Metric ton refers to 1,000 kilograms, and stone is treated as the UK standard 14 pounds.
This tool converts mass-style units only, so liquid measures and fluid ounces belong in the volume converter instead.

Unit handling

Weight accepts numeric values.
From Unit accepts one of the configured options.
To Unit accepts one of the configured options.

Rounding rules

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