Energy 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

All units are converted to Joules (the SI unit) first. * **1 Calorie (cal)** = 4.184 Joules * **1 Food Calorie (kcal)** = 4,184 Joules * **1 kWh** = 3,600,000 Joules

Test cases

Default input regression check

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

Inputs

Energy Amount: 100
From: Kilocalorie (kcal)
To: Kilojoule (kJ)

Expected outputs

Converted Value: 418.4
Logic: 1 kcal ≈ 4.184 kj

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

All supported units are converted through joules using standard accepted energy factors.
Nutrition-style Calories are represented as kilocalories, while lowercase calories represent the smaller physics unit.
The tool converts totals only and does not estimate energy production, losses, or efficiency.

Unit handling

Energy Amount accepts numeric values.
From accepts one of the configured options.
To accepts one of the configured options.

Rounding rules

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