Volume 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 a base unit (Liters) first. * **1 US Gallon** = 3.785 Liters * **1 US Quart** = 0.946 Liters * **1 US Cup** = 0.237 Liters (approx 240ml)
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Volume: 1
- From: Liter (L)
- To: Gallon (US)
Expected outputs
- Converted Value: 0.26
- Factor: 1 l ≈ 0.2642 gal
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
- US customary liquid units are used for gallons, quarts, pints, cups, and fluid ounces.
- The calculator converts scalar volume only and does not account for density, temperature expansion, or ingredient packing.
- Milliliter and liter conversions follow metric definitions exactly.
Unit handling
- Volume 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.
