Crypto Converter

Instantly convert between any two cryptocurrencies (or a coin and US dollars) using live market prices. Enter an amount, pick the currencies, and the rate updates automatically.

In short: The Fox Periodical crypto converter turns any cryptocurrency into another coin — or into US dollars — at live mid-market rates. Type an amount, choose two currencies, and the result, the reverse rate and a quick-reference conversion table update instantly. It is free, needs no sign-up, and runs entirely in your browser.

What the crypto converter does

A crypto converter answers one of the most common questions in the market: "how much is this actually worth?" Our converter prices every supported asset against the US dollar from the same live feed that powers our live markets table, then calculates the exact cross-rate between any two currencies you select. Want to know what 0.25 Bitcoin is in dollars, how many Solana you could swap for one Ethereum, or the combined value of your altcoins? You get an instant, accurate figure with no spreadsheet and no maths.

Unlike a static price ticker, the converter is bidirectional and interactive. It recalculates as you type, lets you flip the pair with a single swap button, offers one-tap shortcuts for the most popular pairs, and prints a conversion table for round amounts so you can sanity-check an order at a glance.

How to use the crypto converter (step by step)

  1. Enter an amount in the first field — for example 0.5. Decimals are fine, right down to satoshi-level precision.
  2. Choose the currency you are converting from in the first dropdown (e.g. Bitcoin).
  3. Choose the currency you want the result in in the second dropdown (e.g. US Dollar, or another coin).
  4. Read the result instantly, along with the live exchange rate shown in both directions.
  5. Swap or shortcut. Tap the swap (⇅) button to reverse the pair, or click a popular-pair chip such as BTC → USD or ETH → BTC to jump straight there.
  6. Use the conversion table beneath the result to see common amounts (1, 5, 10, 50, 100, 1,000) priced at once.

Most-searched crypto conversions

These are the conversions people look up most often. Each one works the same way — pick the two currencies and enter your amount. The converter handles the live pricing for you.

How crypto conversion works (the cross-rate formula)

Every asset in the converter is first priced in US dollars. To convert from coin A to coin B, the tool divides one dollar price by the other:

result = amount × (USD price of A) ÷ (USD price of B)

Suppose Bitcoin is trading at $74,000 and Ethereum at $2,000. Then 1 BTC = 74,000 ÷ 2,000 = 37 ETH. Reverse it and 1 ETH = 2,000 ÷ 74,000 = 0.027 BTC. Because both legs come from the same live feed, the cross-rate is internally consistent no matter which direction you convert or which pair you pick.

Mid-market rate vs the price your exchange shows

A converter displays the mid-market rate — the midpoint between the best buy (bid) and best sell (ask) prices across the market. It is the fairest single number to quote, but it is not necessarily the price you will execute at on an exchange. Several costs sit between the reference rate and your final amount:

CostWhat it isRoughly how much
Bid-ask spreadThe gap between buy and sell pricesTiny on majors; wider on small-cap coins
Trading feeThe exchange's commission per trade~0.1%–0.6% per side
Withdrawal/network feeCost to move coins off the platformFlat fee per asset/network
SlippagePrice movement between quote and fillGrows with order size and volatility
Treat the converter as an accurate reference, then check your exchange for the fee-inclusive amount.

To model these costs on a real trade, use our profit calculator, which lets you enter buy and sell fees and shows your break-even price.

Understanding spread, slippage and liquidity

On deep, liquid markets like BTC/USD, the spread is a fraction of a percent and a typical retail order fills at almost exactly the mid-market rate. On thinly traded altcoins, the order book is shallow: a moderately sized order can "walk the book," filling at progressively worse prices. That difference between the expected price and the average fill price is slippage. The takeaway: for large conversions, the converter's figure is your best-case reference — budget for the spread and slippage to move the real rate against you.

When to use a crypto converter

  • Valuing a holding — see what your coins are worth in dollars right now.
  • Sizing an order — work out how many coins a dollar budget buys before you place a trade.
  • Comparing offers — convert an OTC or peer-to-peer quote to the market rate to judge whether it is fair.
  • Tracking ratios — follow pairs like ETH/BTC to gauge how altcoins are performing against Bitcoin.
  • Planning a DCA buy — convert your recurring dollar amount into coins; our DCA calculator takes it further.

Supported cryptocurrencies

The converter supports the leading cryptocurrencies by market capitalisation — including Bitcoin (BTC), Ethereum (ETH), the major stablecoins (USDT, USDC), BNB, Solana (SOL), XRP, Cardano (ADA), Dogecoin (DOGE) and dozens more — plus the US dollar. You can browse every supported asset, with full price history and stats, on our coins page.

Common mistakes to avoid

Watch out for these:
  • Treating the rate as your execution price. The mid-market rate excludes fees and spread — your exchange total will differ.
  • Forgetting prices move 24/7. A quote left on screen for minutes can drift; refresh before acting on it.
  • Mixing up units. 1 BTC is very different from 1 satoshi (0.00000001 BTC). Double-check decimals on large amounts.
  • Assuming a low unit price means "cheap." Price tells you nothing without supply — see our compare coins tool.

Key terms

Mid-market rate
The midpoint between the best bid and ask — the reference price the converter shows.
Cross-rate
The exchange rate between two assets derived through a common currency (here, the US dollar).
Spread
The difference between the highest buy price and the lowest sell price at a given moment.
Slippage
The gap between the price you expect and the average price your order actually fills at.
Gwei / satoshi
Tiny denominations: a satoshi is 0.00000001 BTC; Gwei is a small unit of ETH used for gas.

Tips for accurate conversions

  • Refresh before you act on a quote that has been on screen for a while — crypto never closes.
  • For large conversions, mentally add the spread and slippage; the real rate may move against you.
  • Use the conversion table to spot-check round numbers before placing an order.
  • For coin-to-coin swaps, watch the ratio (e.g. ETH/BTC) rather than each dollar price in isolation.

Frequently asked questions

Is the converter live?

Yes — rates come from live market data, cached briefly for speed.

Which coins are supported?

The top cryptocurrencies by market cap, plus USD.

How do I convert Bitcoin to USD?

Enter the amount of Bitcoin, choose Bitcoin in the first dropdown and US Dollar in the second. The dollar value appears instantly, along with the live BTC/USD rate in both directions.

Can I convert one cryptocurrency directly into another?

Yes. Select any supported coin in each dropdown — for example ETH to SOL — and the converter calculates the cross-rate automatically by pricing both legs in US dollars.

How accurate is the crypto converter?

It uses live mid-market prices aggregated from major exchanges, cached only briefly for speed, so it reflects the market to the moment shown. The exact amount you receive on an exchange can differ slightly because of fees, the bid-ask spread and slippage.

Why is the converter rate different from my exchange price?

The converter shows the mid-market rate — the midpoint of the order book. Your exchange adds a trading fee, the bid-ask spread and, on larger orders, slippage, so the fee-inclusive total you pay or receive will be a little different.

Does the converter include trading or withdrawal fees?

No. It shows the market rate only. Exchange trading fees, network/withdrawal fees and spread are separate. To factor those in, use our profit calculator.

How many decimal places can I convert?

You can enter very small fractions, down to satoshi-level precision for Bitcoin (0.00000001 BTC), which is useful for micro-amounts and gas-level sums.

Can I convert USD into crypto?

Yes — the converter is fully bidirectional. Put US Dollar in the first dropdown and a coin in the second to see how much crypto a given dollar amount buys, or tap the swap button to reverse any pair.

Does it support stablecoins like USDT and USDC?

Yes. Stablecoins are included, which is handy for checking how closely a coin is tracking its intended $1 peg at any moment.

What is the ETH/BTC ratio and why does it matter?

It is the price of Ethereum expressed in Bitcoin. Many traders watch it to judge whether altcoins are gaining or losing ground against Bitcoin, independent of the dollar.

How often do the prices update?

Prices refresh continuously from the live market feed while the page is open and recalculate the instant you change an amount or currency.

Is the crypto converter free to use?

Completely. There is no sign-up, no limit on the number of conversions, and the tool runs entirely in your browser.

Can I use the converter on mobile?

Yes. It is fully responsive, and the conversion table scrolls horizontally so everything stays readable on a phone.
