Frequently Asked Questions
Do these conversion rates include bank spreads or transaction fees?↓
No. These are mid-market interbank benchmark rates. Retail credit cards and airports typically charge a 2%–4% foreign transaction markup above mid-market rates.
How frequently are currency rates updated?↓
Rates are committed daily from public central bank APIs with an offline committed JSON fallback to ensure deterministic, zero-latency client calculation.
What occurs if I convert a currency into itself (e.g. USD to USD)?↓
The exchange rate is exactly 1.0000, and the converted amount matches the input amount.
What is a limitation of static daily forex rates?↓
Forex markets trade continuously 24/5; daily rates reflect closing mid-market fixings rather than second-by-second intra-day ticks.
