How the Bitcoin converter works
Enter an amount in any field – bitcoin, satoshis, US dollars or euros – and all other values are converted instantly using the current BTC exchange rate. One bitcoin equals 100 000 000 satoshis (sats), so the converter is also handy for pricing everyday amounts in sats.
Pick a purchase date to see what the amount cost back then, what it is worth today and its highest and lowest value since. The converter uses the daily closing price of that day.
Questions
How many satoshis are in one bitcoin?
One bitcoin is divided into 100 000 000 satoshis. A satoshi (sat) is the smallest unit recorded on the Bitcoin blockchain and is named after Bitcoin's creator, Satoshi Nakamoto.
How do I convert sats to euros or dollars?
Divide the number of sats by 100 000 000 to get the amount in BTC and multiply it by the current BTC price. The converter does this automatically – just type the amount into the Satoshis field.
Can I calculate the value of bitcoin on a past date?
Yes. Pick a date under “When did you buy?” or use one of the shortcuts. The converter uses the daily closing price of that day, so you see what your bitcoin cost back then and what you would have gained or lost since.
How current are the exchange rates?
Rates come from mempool.space and are refreshed automatically in the background. The line above the converter and the note at the end of the page show which BTC price and time were used.
