Crypto Converter

How crypto conversion works

Converting between cryptocurrencies is almost always a two-step operation through a reference currency. Prices of each asset are quoted against US dollars, so a cross rate is simply one USD price divided by the other. Converting Bitcoin to Ethereum means converting BTC to dollars, then dollars to ETH.

This converter does exactly that, using a single snapshot of prices so both legs of the cross rate are consistent. Using prices taken at different moments is one of the most common ways to misjudge a swap.

Prices are cached briefly to keep the page fast, and every result shows the timestamp so you can judge whether it is still current.

What the quoted price does not include

The mid-market price is a reference point. What you actually receive when swapping assets is almost always less, sometimes meaningfully so:

• Exchange trading fees, typically 0.1% to 0.6% per trade, higher for card purchases and "instant buy" features.
• Spread between buy and sell prices, especially on low-volume pairs and small-cap tokens.
• Network fees, which for Bitcoin and Ethereum can swing from a few cents to tens of dollars depending on congestion.
• Withdrawal fees charged by the exchange, and slippage on large orders that move the market against you.
• Tax consequences — in the United States, disposing of crypto is a taxable event, whether you sell it for dollars or swap it for another token.

Why prices differ between sources

Crypto trades continuously across dozens of exchanges with no single official close. Each venue has its own order book depth, fiat pairs, regional demand and withdrawal friction, so quoted prices naturally drift apart.

A stablecoin such as USDT or USDC tracks the dollar closely by design, but it is not perfectly fixed — redemption mechanics, reserve composition and periods of stress all create small deviations. Those deviations matter a great deal to arbitrage traders and very little to someone checking a portfolio value.

Using the custom price override

Because the tool lets you set your own price per unit, you can answer questions the live feed cannot. What would a Bitcoin purchase be worth at $250,000? How much Ethereum could you buy during the 2022 lows? What does your position look like if a token drops 40%?

Override the price, leave the amount unchanged, and the whole conversion table recalculates instantly.
