Frequently Asked Questions
How do I convert one cryptocurrency directly into another, like ETH to BTC?
Set the "from" currency to the coin you hold and the "to" currency to the coin you want, then enter the amount. Even though both sides are crypto, the converter bridges them through the US dollar: it takes each coin's live USD price, then divides the source price by the target price to get the cross-rate. So 1 ETH worth $3,000 against a BTC worth $60,000 returns 0.05 BTC. This mirrors how exchanges quote pairs, since most crypto-to-crypto liquidity is routed through a dollar or dollar-pegged asset anyway, rather than as a single native pair. Keep in mind the figure is a mid-market reference, not an executable quote, so a real swap will differ once spreads and trading fees are applied. Pick your two coins above and enter an amount to see the converted value instantly.
Why does the converted price change when I refresh the tool?
Cryptocurrency markets trade 24/7 with no opening or closing bell, so prices move constantly, including overnight and on weekends. This converter pulls current rates from the public CoinGecko API when you open it, and the refresh button re-fetches the latest figures on demand. That means the same conversion can return a slightly different result minutes apart, which is normal and reflects genuine market movement rather than a bug. The "last updated" timestamp under the result tells you exactly when the prices were pulled, so you always know how fresh the numbers are. For volatile coins, the gap matters, so refresh right before you rely on a figure for a decision or a quote. Use the refresh icon at the top of the converter whenever you want to re-pull live prices and update every conversion on the page.
What does the 24-hour change percentage next to my conversion mean?
When you convert a cryptocurrency into a fiat currency, the tool shows a percentage labelled "(24h)" beneath the result, coloured green for a gain and red for a loss. This is the coin's price movement over the trailing 24 hours against that fiat, sourced live from CoinGecko alongside the price itself. A reading of +4.20% means the asset is worth about 4.2% more than it was a day earlier, while a negative figure shows a decline. It is a quick volatility gauge that helps you judge whether the rate you are looking at is unusually high or low compared with yesterday. The same percentages appear in the Live Rates table for the top coins. Convert any crypto amount to USD or another fiat above to see its 24-hour change at a glance.
How do I quickly enter small Bitcoin amounts like 0.001 BTC?
Typing tiny crypto fractions by hand is fiddly, so the converter includes quick-amount buttons set to 0.001, 0.01, 0.1, 1, and 10. Tapping one instantly fills the amount field with that value in the currently selected "from" currency, which is ideal for checking what a fraction of a Bitcoin or a stack of tokens is worth without counting decimal places. You can still type any custom amount manually, and the result formats intelligently: large numbers get thousands separators, while very small values switch to extra decimals or scientific notation so nothing rounds away to zero. There is also a Swap button to flip the from and to currencies in one click and check a pair in both directions. Try the quick-amount buttons above to price common crypto fractions in a second.
Is this crypto converter accurate enough to use for tax or invoicing estimates?
The converter uses live mid-market prices from CoinGecko, which aggregates rates across many exchanges, so the figures are accurate for estimation, planning, invoicing in stablecoins, or sanity-checking what a balance is worth. However, it shows reference rates, not the price you would actually transact at. Real exchanges add spreads, trading fees, and slippage, so an executable buy or sell will differ from the mid-market number shown here. For tax reporting, jurisdictions also often require a specific price source or the exact rate at the moment of each transaction, so confirm your local rules and keep dated records. Treat this tool as a fast cross-currency reference rather than an official quote, and consult a tax professional for filings. Enter your amount above to get a clean, current estimate in seconds.

About the Cryptocurrency Converter
The Cryptocurrency Converter is a free tool for translating an amount in one currency into another across the crypto and fiat worlds. Pick a "from" and "to" currency, type an amount, and it returns the converted value along with the asset's 24-hour price move. It covers more than 20 cryptocurrencies and 10 major fiat currencies, so you can answer questions like "how much is 0.5 BTC in euros?" or "what is 100 USD worth in Solana?" in a single step.
It is built for anyone who deals with crypto prices without wanting to log into an exchange: holders sanity-checking a portfolio, freelancers invoicing in stablecoins, shoppers pricing an NFT, or people who simply want a quick, readable conversion. There is no sign-up, no account, and no software to install.
What it converts
The converter handles every direction between the supported assets, not just crypto-to-dollar:
- Crypto to fiat — for example BTC, ETH, or DOGE into USD, EUR, GBP, JPY, INR, and others.
- Fiat to crypto — go the other way to see how much coin a cash amount buys.
- Crypto to crypto — convert between two coins (the rates are bridged through USD).
- Fiat to fiat — standard currency pairs are supported too.
Supported cryptocurrencies include Bitcoin, Ethereum, Tether, USD Coin, BNB, Solana, XRP, Dogecoin, Cardano, Avalanche, Polygon, Polkadot, Litecoin, Chainlink, Uniswap, TRON, Stellar, Cosmos, Monero, NEAR, Shiba Inu, and Lido Staked Ether. Fiat options are USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, INR, and BRL.
Live rates, not stale tables
Prices come from the public CoinGecko API and load when you open the tool. Because the data is fetched live, you are working with current market rates rather than a hard-coded snapshot. A "Live Rates (vs USD)" panel lists the top coins with their dollar price and 24-hour percentage change, color-coded green or red, and a timestamp shows exactly when the figures were last refreshed. A refresh button re-pulls the latest prices whenever you want them.
Two small touches speed up everyday use. A Swap button flips the "from" and "to" currencies instantly, which is handy for checking a pair in both directions. Quick-amount buttons (0.001, 0.01, 0.1, 1, and 10) fill the input with common values so you don't have to type small crypto fractions by hand. Results are formatted intelligently — large numbers get thousands separators, while sub-cent values fall back to more decimal places or scientific notation so nothing is rounded away to zero.
Why a quick converter matters
Crypto prices are volatile, and the figure that mattered an hour ago may not match the one on screen now. A few realities worth keeping in mind:
- Bitcoin and most coins trade 24/7. Unlike stock markets, crypto never closes, so a "live" rate is genuinely live — including weekends and overnight.
- Cross-rates can drift. Converting one coin to another through USD is the standard method, but the price you actually pay on an exchange will differ once spreads and fees are added.
- This is a reference, not a quote. The converter shows mid-market style rates for estimation and planning. It does not place trades, and an exchange's executable price will include its own fees and slippage.
For tax estimates, invoicing, or simply understanding what a balance is worth, a fast cross-currency check beats opening a full trading platform.
Privacy and how it works
The amounts you enter and the currencies you pick stay in your browser — nothing about your conversions is sent to a server we control. The one external call the tool makes is a read-only request to CoinGecko to fetch current prices; that request carries no personal data, just the list of coins and fiats to quote. There is no login, no tracking of your inputs, and no usage limit.
