Why are conversions needed between cup (US) and cup (metric)?

Because the US cup and metric cup have different volume definitions, conversions ensure correct ingredient amounts when adapting recipes or labeling across measurement systems.

Is the metric cup an official international unit?

No, the metric cup is a non-SI unit commonly used for culinary purposes in metric-using countries but is not an official international standard.

Can I rely on this conversion for baking accuracy?

For baking requiring high precision, mass measurements are recommended since volume conversions between cups might not be sufficiently exact.
