Crypto Calculator

A crypto calculator converts an amount of cryptocurrency into a regular currency such as US dollars, or back again, at the current market rate. Choose a coin such as Bitcoin or Ethereum, choose a currency and enter an amount in either field. The result is a market reference rate and does not include fees.

How do you use the crypto calculator?

Choose a coin, choose a currency and type an amount. The calculator converts in both directions, so you can start from the crypto you have in mind or from the money you want to spend.

1. Choose a coin. Open the crypto menu in the calculator and search by name or by ticker symbol, for example ETH for Ethereum or SOL for Solana.
2. Choose a currency. Open the currency menu and pick US dollars (USD), euros (EUR), British pounds (GBP) or another currency.
3. Enter an amount in either field. Type an amount of crypto to see what it is worth, or an amount of money to see how much crypto it converts to. The other field updates as you type.
4. Treat the result as a guide. It uses the market reference rate and does not include fees. When you are ready to buy, see crypto prices and payment options. The fees for your order are shown before you confirm.

What are today’s crypto reference rates?

Here is what one unit of other popular coins is worth in US dollars at the same reference rate:

1 ETH =$2,408.58+4.08% (24h)

1 USDT =$0.9989+0.02% (24h)

1 USDC =$0.9998+0.00% (24h)

1 XRP =$1.31+2.64% (24h)

1 SOL =$95.87+3.35% (24h)

1 DOGE =$0.0764+2.38% (24h)

The calculator loads the latest rate when you open the page, so reload the page for a fresh rate. The 24-hour change next to each price is history, not a forecast. Past performance does not predict future results.

How does the calculator convert crypto to dollars?

It multiplies or divides by the market reference rate, which is the price of one coin. To turn crypto into dollars, the calculator multiplies the amount of crypto by that price. To turn dollars into crypto, it divides the dollar amount by the price.

Here is an example with round numbers. Say one coin has a reference rate of $2,000 (an example, not a real price):

• Crypto to dollars: 0.5 coins × $2,000 = $1,000.
• Dollars to crypto: $100 ÷ $2,000 = 0.05 coins.

For other currencies, the calculator starts from the US dollar rate and converts it with a currency exchange rate. The euro value of a coin, for example, is its US dollar value multiplied by the number of euros that one US dollar buys. Crypto prices are usually quoted as trading pairs such as BTC/USD; the guide to how crypto trading pairs work explains the idea.

Why are crypto amounts often so small?

Because most coins can be split into tiny units, you rarely need a whole coin. One bitcoin equals 100,000,000 satoshis, so one satoshi is 0.00000001 BTC. One ether (ETH) equals 1,000,000,000 gwei, and the smallest unit of ether, called wei, is 0.000000000000000001 ETH.

Small units make everyday amounts easier to read. To convert satoshis directly, use the satoshi calculator, or read Bitcoin units explained for BTC, mBTC, bits and sats.

Why can the rate differ from other websites?

Because there is no single official price for a cryptocurrency. Each exchange has its own buyers and sellers, so the latest trade price can differ slightly from one exchange to the next, and prices move all the time.

On any market, the highest price a buyer offers and the lowest price a seller accepts are rarely the same. The gap between them is called the spread. The calculator shows one reference rate, so it is a guide for comparing amounts, not a quote. Prices can also change quickly, which is why volatility matters when you buy.

Does the crypto calculator include fees?

No. The rates shown are market reference rates and do not include fees. Coinmama does not add its own fee. All fees are shown before you confirm your order.

Coinmama is a cryptocurrency exchange. For how purchase fees work, see Coinmama fees and Fees & Charges.

Which coins can you convert?

The calculator covers Bitcoin, Ethereum, stablecoins such as Tether (USDT) and USD Coin (USDC), and many other coins with market data. Search the coin menu by name or ticker symbol to find the one you want.

Stablecoins are designed to stay close to a fixed value, usually one US dollar. Their price can still move away from $1 when markets are under stress, so check the rate like any other coin. Learn more in What is a stablecoin?

A coin in the calculator is not necessarily a coin you can buy on Coinmama, and availability can depend on where you live. Check the cryptocurrencies Coinmama offers and where Coinmama is not available.

Which Coinmama calculator should you use?

Use this crypto calculator to convert any coin in the list or to compare coins in one place. For a single coin, the dedicated calculators add conversion tables and unit guides:

• Bitcoin calculator: convert BTC to US dollars and back, with ready-made conversion tables.
• Ethereum calculator: convert ETH to US dollars and see ETH units such as gwei explained.
• Satoshi calculator: convert satoshis, the smallest unit of Bitcoin, to US dollars.
• Bitcoin profit calculator: estimate the profit or loss on a past Bitcoin purchase. It looks back only; past performance does not predict future results.
