Comment l'utiliser
Type an amount
Use the input on the left. Decimals work - try 0.001 BTC to see what a satoshi-scale amount looks like.
Pick the two assets
Searchable comboboxes list all 20 crypto assets and 10 fiat currencies. Switch the source from BTC to ETH (or any combination) and the result re-computes instantly.
Check the multi-target table
Below the headline, the same amount is shown in five popular targets (BTC, ETH, USD, EUR, USDT) at once - useful when you're checking a price against multiple anchors.
Qu'est-ce que c'est ?
A cryptocurrency converter is a price calculator: amount of asset A times the current price of A times the inverse of the current price of B equals amount of asset B. The interesting part is the price source - exchanges differ by a few basis points, and a 'mid-market' average sits between them. This tool uses a frozen snapshot of mid-market prices, which is fine for back-of-the-envelope conversions and budgeting but is not suitable as a basis for actual trades.
Quand l'utiliser
Pricing out a crypto holding in your home fiat currency. Translating a token's price (announced in USD) into your local currency. Quick sanity checks before clicking 'swap' on a DEX - is the rate the DEX is quoting reasonable? Estimating gas fees in fiat. Calculating how many satoshis equal a coffee. Comparing portfolio values across multiple chains.
Erreurs courantes
Trusting a static rate for a market order - crypto can move 5% in an hour during a news event. Confusing market cap with circulating supply (this tool only does price-per-unit math; market-cap calculations need a separate supply lookup). Forgetting that on-chain fees come out of your transfer - the 'amount sent' is the amount before fees, not what lands at the destination.
FAQ
- Are these prices live?
- No. We use a static snapshot to keep the tool fast, free and offline-capable. Crypto is volatile - the snapshot's 'as of' date is shown below the converter. For trade-execution prices, always check an exchange.
- What's a satoshi?
- One satoshi is 1 / 100,000,000 of a Bitcoin (eight decimal places). Type a fractional BTC value or use a satoshi-friendly converter pair like 'BTC -> USD' with a fractional input.
- Why are USDT and USDC always around $1?
- They're stablecoins designed to track the US dollar. Brief deviations happen, but for converter purposes they're $1 to a tenth of a cent.
- Do you support obscure coins?
- We track the top 20 by market cap plus the three major stablecoins, which covers most search demand. For long-tail tokens, a dedicated crypto exchange or aggregator will be more accurate and current.
