Converters & calculators
Bitcoin Tools
Unit converters, a fee calculator, a halving estimator and a hashrate converter — all running on live data, none requiring an account.
Live inputs: BTC — · block height —. Every calculation runs in your browser. Nothing you type is stored or sent anywhere.
Converter
BTC, satoshis and dollars.
Type into any field and the other two follow. One bitcoin is exactly 100,000,000 satoshis — that is a protocol constant, not an exchange rate.
Fee calculator
What your transaction will actually cost.
Fees are charged per virtual byte, so the shape of your transaction matters more than the amount you are sending. Pick a transaction type to price it at each current confirmation target.
Estimated size: —

Block height estimator
When will the chain reach a height?
Enter any block height to see how far away it is, roughly when it will be reached, and what the block subsidy will be at that point. Defaults to the next halving.

Hashrate converter
TH/s, PH/s, EH/s.
Mining hardware is quoted in terahashes, pools in petahashes, and the whole network in exahashes. Each step is a factor of a thousand.
Assumptions used on this page
- Time estimates assume Bitcoin’s ten-minute target block interval. Real intervals vary, and difficulty only corrects the average every 2,016 blocks.
- Transaction sizes are typical values for each script type. Your wallet’s exact size depends on how many inputs it needs to spend.
- Fee rates are current network estimates and change continuously. A transaction broadcast in an hour may face a different market.
- Dollar figures use the live streamed price and are indicative, not a quote.
