Recipe Unit Converter — illustrative example

INPUT
Convert 500 grams to kilograms and 2 US cups of water to milliliters using 236.588 ml per US cup.

RESULT
500 g = 0.5 kg.
2 US cups = approximately 473.176 ml under the supplied convention.
For flour or other ingredients, do not infer grams from this water example.

REVIEW
Recipe conversions must identify the unit system and ingredient. Mass-to-volume conversion requires a suitable density or verified reference, so cups of different ingredients cannot share one universal gram value.

This is a teaching example, not a live execution record.
