About the Satoshi to BTC Converter
A satoshi, or sat, is the smallest piece of a bitcoin: one hundred millionth of a BTC. Wallets, exchanges and fee tools show amounts in different units, which makes it easy to misplace a decimal point. This converter turns any amount into BTC, millibitcoin (mBTC), bits (microbitcoin) and satoshis at once. It uses exact whole-number maths, so 0.1 BTC is exactly 10,000,000 sats with no rounding errors. If you type a price for one bitcoin in your own currency, it also shows what the amount is worth. Nothing is looked up or sent: all the work happens in your browser.

The Bitcoin unit ladder
Bitcoin amounts are stored as whole satoshis. Everything else is a display choice. One BTC is 1,000 mBTC, which is 1,000,000 bits, which is 100,000,000 satoshis. Because the ratios are all powers of ten, converting is only a matter of moving the decimal point, but it is very easy to move it the wrong way when you are in a hurry.
The converter does the shifting with exact integer maths. Computers that use ordinary decimal numbers can show 0.1 + 0.2 as 0.30000000000000004. Bitcoin amounts avoid this by counting satoshis, and so does this page.
Where each unit shows up
- BTC is the headline unit on exchanges and in news.
- Satoshis are used by fee tools and on-chain explorers, for example a fee of 1,540 sats.
- Bits appear in some mobile wallets that wanted whole-number balances for everyday amounts.
- mBTC is rare today but still appears in older software and guides.
Avoiding costly mistakes
Check the unit before you send. A wallet that shows sats will treat 1,000 as one thousand satoshis, about a few cents, while 1,000 mBTC is a full bitcoin. When you type an amount into a payment form, confirm the final BTC amount on the confirmation screen.
Pair this page with the other bitcoin tools on the site. Look at the cost of a transaction with the Bitcoin Fee Estimator, check a destination with the Bitcoin Address Validator, and compare today's value with the Bitcoin Price Converter. For a general amount-in-another-unit job, the Unit Converter handles length, weight and more.

Frequently asked questions
How many satoshis are in one bitcoin?
There are 100,000,000 satoshis in one bitcoin. One satoshi is 0.00000001 BTC.
How do I convert sats to BTC?
Divide the number of satoshis by 100,000,000, or move the decimal point eight places to the left. For example 250,000 sats is 0.0025 BTC.
What is a bit in Bitcoin?
A bit is one millionth of a bitcoin (0.000001 BTC), which is 100 satoshis. Some wallets and apps show small amounts in bits because the numbers are easier to read.
What is an mBTC?
A millibitcoin is one thousandth of a bitcoin, which equals 100,000 satoshis. It is the bitcoin equivalent of a millilitre or a millimetre.
Why can't I type a fraction of a satoshi?
On the Bitcoin base layer, the satoshi is the smallest unit and cannot be split. If you type a fraction in the sats box, the tool asks for a whole number. You can use the BTC box for up to eight decimal places.
Does this tool fetch the current Bitcoin price?
No. You type any price for one bitcoin, so the answer always matches the number you chose. To fetch a live price, use the Bitcoin Price Converter.
Is the money value financial advice?
No. It is simple multiplication of the amount by the price you entered. Prices change all the time, and real exchange rates and fees will differ.
