CHF EUR Converter

Converts between CHF and EUR using either live exchange rates or a user-supplied override. The tool is a focused FX calculator designed for quick, repeatable results in financial planning, invoicing, and travel budgeting. It outputs a precise converted amount in the target currency and exposes the rate used for auditability. By avoiding UI frills, it remains predictable and easy to automate in reporting pipelines.

Conceptually, it maintains a single exchange rate between CHF and EUR at calculation time. When live mode is enabled, it queries a trusted rate source for EUR per CHF and applies that rate to the input amount. If an override_rate is provided, the system uses that value instead. The result is rounded to two decimals by default and paired with the rate_used and a timestamp.

Beneficiaries include accounting teams who reconcile expenses, procurement staff buying in CHF or EUR, freelancers invoicing clients across borders, and travelers comparing prices. The differentiator is explicit rate provenance (rate_used) and a straightforward, auditable output that can be embedded in spreadsheets or automated reports.

Core features include a compact multi-field input, live vs manual rate support, explicit rate_used, and a simple, deterministic conversion formula. Use cases cover budgeting, invoicing, expense validation, and price comparisons where currency precision and auditability matter.
