Currency Converter
Convert between 50+ currencies with reference rates as of a known date. No live API, no tracking — useful for quick freelance estimates and quotes. Always verify before invoicing.
What this is — and isn't
This is a quick reference currency converter. You pick a source currency, pick a target, enter an amount, and the tool divides by the source's EUR rate and multiplies by the target's EUR rate. That's it. The rates are hard-coded in the page — there is no network call, no API key, no tracking.
It is not a forex terminal. The rates were correct on the date shown beneath the result and are updated roughly quarterly. Real bank rates move every second and include a margin (typically 0.5–3% for retail, much tighter on FX desks), card-network fees, and weekend mark-ups. Before invoicing a client or sending an actual payment, look up the current rate from your bank, Wise, or a public FX feed.
Why we don't fetch live rates
Almost every "free" live-rate API in the wild logs the IP, referrer, and currency pair you queried. For a tool meant to be useful to freelancers checking quote ballparks all day, that's a metadata leak that compounds: each refresh is one more data point about your client mix and your typical contract size sitting in someone's database. A static reference table avoids the problem completely — your queries never leave the browser. The tradeoff is accuracy: don't blindly trust the result for transactions.
Common gotchas
- Pegged currencies look fixed but aren't always. BGN is hard-pegged to EUR at 1.95583 (and has been for years). DKK and HKD are pegged within bands. But the relationship can change overnight — the Swiss Franc cap was abandoned suddenly in 2015. Don't assume a peg holds for the future just because it held last year.
- EUR-cross compounds error. Every conversion routes via EUR (USD → JPY = USD/EUR × EUR/JPY). Tiny rounding errors in two rates compound on illiquid pairs. The result is fine for ballpark; not fine for accounting.
- Mid-rate ≠ what you get. The published "mid-rate" is the midpoint between buy and sell. Your bank quotes a buy price and a sell price; the spread between them is their margin. Card networks add another 1–3% on top. Expect to receive 1–4% less than the mid-rate quoted here.
- Inflation-driven currencies move fast. ARS (Argentine Peso), TRY (Turkish Lira) and similar can move 5–10% in a month. A snapshot rate dated three months ago could be quite wrong. Treat the date label seriously.
- Cash vs digital differ. Tourist cash bureaus, ATM withdrawals abroad, and card transactions each have different rate structures. The "mid-rate" applies most closely to bank transfers and FX-desk trades; cash conversion in an airport is typically 5–10% worse.
When this tool is useful
- Drafting a freelance quote for a client in another country and you want a ballpark in your home currency.
- Reading a foreign-currency invoice and quickly checking whether it's roughly what you expected.
- Comparing prices on two sites listed in different currencies.
- Sanity-checking that a wire transfer landed in the right ballpark after spread.
It is not useful for: hedging, FX trading decisions, tax filings (use the rate published by your tax authority for the relevant date), or anything where being off by 1–3% matters.
