About Satoshi / BTC Converter
The Satoshi to BTC Converter translates a Bitcoin amount between its common denominations: satoshi, bit (also called μBTC), mBTC, and BTC. Enter an amount, choose the unit it is in, pick the unit you want, and the converted value appears instantly with a Copy button. The conversions are based on the fixed relationships defined by the Bitcoin protocol, so the results are exact whole-of-protocol values rather than market estimates.
The denomination scale is anchored on the satoshi, the smallest unit Bitcoin can record. One BTC equals 100,000,000 satoshis. A bit equals 100 satoshis, an mBTC (milli-bitcoin) equals 100,000 satoshis or one thousandth of a BTC, and a bit is one millionth of a BTC, which is why it is also written μBTC. Because every unit is a fixed power-of-ten multiple of the satoshi, conversion is pure arithmetic and never depends on price. Satoshi results are shown as whole numbers, and the other units display up to eight decimal places, matching Bitcoin's smallest divisible amount.
The tool is handy for reading on-chain amounts, where balances and fees are often denominated in satoshis, for setting Lightning Network amounts that are typically expressed in sats, and for double-checking an mBTC or bit figure quoted in a wallet or article. An optional BTC price field lets you enter a current dollar price you supply yourself to see the approximate USD value of the amount; this is a convenience multiplication, not a live quote, and it is handy for translating a fee shown in sats into a rough fiat cost or for sanity-checking a payment amount.
Note that the USD figure is only as accurate as the price you type, since the tool fetches no market data and stores no past prices. The denomination conversions themselves are exact and fixed by the protocol, so they do not change, but the dollar value is a snapshot estimate that goes stale as the market moves, and it is not financial advice. Everything runs locally in your browser, so the amounts and price you enter never leave your device and the tool keeps working even offline.
Frequently Asked Questions
- How many satoshis are in one Bitcoin?
- There are exactly 100,000,000 satoshis (100 million) in one BTC. The satoshi is the smallest unit the Bitcoin protocol can record and is named after Bitcoin's pseudonymous creator, Satoshi Nakamoto. All other denominations in this tool are defined as fixed multiples of the satoshi.
- What is a bit, and why is it called μBTC?
- A bit equals 100 satoshis, which is one millionth of a BTC. Because "micro" means one millionth, a bit is also written μBTC. It was proposed as a more human-friendly unit for small everyday Bitcoin amounts, sitting between the satoshi and the mBTC.
- What is an mBTC?
- An mBTC, or milli-bitcoin, is one thousandth of a BTC, equal to 100,000 satoshis. It is a middle-ground denomination often used when whole-BTC figures would have too many leading zeros to read comfortably.
- Are the conversions affected by the Bitcoin price?
- No. The conversions between satoshi, bit, mBTC, and BTC are fixed by the protocol and are pure arithmetic, so they never change with the market. Only the optional USD value depends on price, and that uses the price you enter yourself.
- How accurate is the USD value?
- The USD value is simply the BTC amount multiplied by the price you type into the optional field. The tool does not fetch live prices, so the result is only as current and accurate as the number you provide. Treat it as a quick estimate, not a real-time quote or financial advice.
- How precise are the results?
- Satoshi amounts are shown as whole numbers because the satoshi is indivisible on-chain. The other units display up to eight decimal places, matching Bitcoin's maximum precision of one hundred-millionth of a BTC. This is enough to represent any valid Bitcoin amount exactly.
- Is my data sent to a server?
- No. All conversions and the optional USD multiplication run in your browser. No amounts or prices are uploaded, and the tool works without a network connection once the page has loaded.
