What the Crypto Converter does
The Crypto Converter translates the value of one asset into another at the latest stored prices. Type a number in either field and the tool immediately shows the equivalent in the paired asset. You can convert between a cryptocurrency and a fiat currency (USD, EUR, GBP) or between two cryptocurrencies.
The primary use case is mental arithmetic at speed: rather than memorising the price of a token and doing the division in your head, you enter the amount you care about and the tool handles the math. It is equally useful for portfolio reviews (what is my total position worth?), transaction planning (how much BTC does $500 buy today?) and relative valuation work (what fraction of a Bitcoin is this altcoin position worth?).
How the conversion works
Both prices are drawn from the same stored reference data, so the result is internally consistent. It does not reflect the exact rate you would receive on any particular exchange — spreads, fees and slippage mean real execution prices differ from any reference price.
Worked example: crypto to fiat
Illustrative — prices will differ at the time you read this
Bitcoin is priced at $65,000. You want to know what 0.05 BTC is worth in USD.
- 0.05 × $65,000 = $3,250
Entering 0.05 in the BTC field shows $3,250 in the USD field instantly. Change to 0.1 BTC: $6,500. The calculator handles fractional amounts that are awkward to compute mentally, especially in satoshis or micro-amounts of altcoins.
Worked example: crypto to crypto
Illustrative — prices will differ
Ethereum is at $3,400, Bitcoin at $65,000. How many ETH is 1 BTC worth?
- BTC/ETH rate: $65,000 ÷ $3,400 = approximately 19.1 ETH per BTC
This is sometimes called the ETH ratio or BTC/ETH ratio. Traders who think in relative terms watch it: when the ratio is high, ETH is “cheap” in BTC terms (or BTC is expensive in ETH terms). When the ratio falls, ETH is gaining on Bitcoin. The converter makes this ratio instant to calculate for any current prices.
Scenario: portfolio value in GBP and BTC terms
Multi-currency portfolio snapshot
You hold 0.35 BTC and 4.2 ETH. BTC = $65,000, ETH = $3,400, GBP/USD = 0.794.
- BTC value: 0.35 × $65,000 = $22,750 ≈ £18,051
- ETH value: 4.2 × $3,400 = $14,280 ≈ £11,338
- Total: $37,030 ≈ £29,389
- BTC-denominated total: 0.35 + (4.2 × $3,400 ÷ $65,000) = 0.35 + 0.2197 = 0.5697 BTC
Tracking the portfolio in BTC terms reveals whether the ETH allocation is gaining or losing relative to the base asset — a question that gets lost when everything is converted straight to fiat. If 0.5697 BTC last month was 0.52 BTC, the ETH position is outperforming Bitcoin in relative terms regardless of what happened to dollar prices.
Common conversion pairs and their uses
| Pair | Typical use case |
|---|---|
| BTC → USD | What is my Bitcoin worth in dollars? |
| ETH → USD | What is my Ethereum worth in dollars? |
| BTC → ETH | Is ETH currently cheap or expensive relative to BTC? |
| USD → BTC | How much Bitcoin does a fixed dollar amount buy? |
| USD → ETH | How much ETH does a given fiat amount buy? |
| Altcoin → BTC | What fraction of a Bitcoin is this altcoin position worth? |
| Altcoin → USD | Is the dollar value of this position meaningful at scale? |
How much Bitcoin is one dollar?
The satoshi: Bitcoin’s smallest unit
Bitcoin is divisible to eight decimal places. The smallest unit — 0.00000001 BTC — is called a satoshi (or “sat”). As Bitcoin’s price rises, dealing in satoshis makes conversions more intuitive at small dollar amounts. At $65,000/BTC:
- 1 satoshi = $0.00065 (about 0.065 US cents)
- 1,000 sats = $0.65
- 10,000 sats = $6.50
- 100,000 sats = $65.00
- 1,000,000 sats (1 million sats) = $650.00
Some lightning network applications and small-payment systems denominate in satoshis rather than BTC or USD, since a satoshi is a more useful unit of account for small transactions when BTC is priced in the tens of thousands of dollars.
Why conversion prices differ between exchanges
The price shown in this tool is a stored reference price, updated on a schedule. The rate you see on any exchange will differ for several reasons:
- Spread. Exchanges maintain a gap between the buy price (ask) and the sell price (bid). The reference price is typically near the mid-point; you buy at the ask and sell at the bid.
- Trading fees. Most exchanges charge 0.1–0.5% per trade, effectively adjusting the net conversion rate by that amount on each side of a trade.
- Slippage. For large orders, executing against the order book moves the average price — you end up receiving a worse rate than the spot price for the first unit.
- Geographic and currency premiums. In some markets, local demand and capital controls push the effective price above or below the global reference rate once converted.
ETH/BTC ratio context: tracking relative performance
The BTC/ETH ratio is a widely watched inter-crypto metric. When it rises (more ETH per BTC), Bitcoin is strengthening relative to Ethereum. When it falls, Ethereum is outperforming. In practice:
- During Bitcoin bull runs, BTC dominance typically rises and the BTC/ETH ratio often increases as capital flows into BTC first.
- During “alt seasons”, ETH and smaller caps often outpace BTC and the ratio falls.
- The ratio can persist at extremes for months — it is a trend indicator, not a mean-reversion signal.
Use the converter to check today’s ratio quickly: enter 1 BTC and see how many ETH it currently buys. Compare that to what it bought a month or a quarter ago to gauge the relative direction.
How to use the converter
- Select the source currency from the left dropdown (e.g. USD, BTC or ETH).
- Select the target currency from the right dropdown.
- Enter an amount in either field — the other updates automatically.
- For portfolio value: convert each holding to USD (or your home currency) and add the totals.
- For relative performance: convert one crypto to another and compare against the same rate from a previous date to see which has outperformed.
Important limits
- Reference prices are updated on a schedule (not in real time). For large trades, always verify the live order book on your exchange before executing.
- The tool does not include exchange fees, spreads or slippage. The actual rate you receive on any trade will be different from the reference price.
- Crypto prices are highly volatile — a reference price from even a few minutes ago can be significantly different from the current tradeable price during volatile market conditions.
Common questions
What is the difference between a “reference price” and an “exchange price”? A reference price is a consensus approximation — typically a volume-weighted average of prices across several major exchanges. An exchange price is the specific bid or ask for your order at that moment on a specific platform. The reference price is reliable for estimation; only the exchange price matters when you are executing a trade.
Can I convert between two altcoins directly? Yes, if both are supported. The tool calculates the cross-rate by routing through USD: amount of A × price of A in USD ÷ price of B in USD = amount of B. Most exchange order books do the same thing when no direct pair exists.
Does the converter handle fiat currencies other than USD? The available fiat currencies depend on the tool’s configuration. Where EUR or GBP are supported, the conversion uses the stored USD/fiat rate alongside the crypto price.
