What does this tool do?

The Crypto Converter provides real-time and recent cryptocurrency exchange rates. It supports over 50 cryptocurrencies including major coins (BTC, ETH, BNB, SOL), stablecoins (USDT, USDC), DeFi tokens, and popular altcoins. Fiat currencies include USD, EUR, INR, GBP, JPY, AUD, CAD, and others. The tool shows current conversion rate, 24-hour price change percentage, and a multi-coin comparison table. You can convert in either direction: from crypto to fiat or from fiat amount to equivalent crypto. Rates update automatically every 60 seconds while the page is open.

How it works

The tool fetches current market data from CoinGecko's free public API, which aggregates prices from ~600+ cryptocurrency exchanges. No API key is required for basic price queries. The fetched data includes current price in various fiat currencies and 24-hour percent change. Conversion math is simple multiplication: fiat = crypto_amount × price_per_unit. The reverse conversion divides by price. Rates lag actual markets by under a minute. The 24-hour change indicates market direction (green for up, red for down). All calculations happen client-side; only price data is fetched from CoinGecko.

Tips & best practices

Frequently asked questions

Where do the rates come from?
CoinGecko's free public API — aggregated from ~600+ exchanges. Rates are volume-weighted averages, lagging actual trades by under a minute.
Are these the rates I'd actually pay?
These are mid-market spot prices. Your exchange will charge a spread (difference between buy and sell price) plus transaction fees — typically 0.1% to 2% total. Expect slightly less favorable rates for actual trades.
Is my conversion data private?
Yes. Rate data is fetched from CoinGecko by your browser. The actual conversion calculations happen in your browser. We have no backend server seeing your amounts or conversions.
How often do rates update?
Every 60 seconds automatically while the page is open. Cryptocurrency markets operate 24/7, so rates change continuously. For trading decisions, use your exchange's real-time interface.
