1 bitcoin = 100,000,000 satoshis (sats), the smallest unit of BTC. A satoshi is to a bitcoin what a cent is to a dollar — except there are 100 million of them, not 100.

Understanding Satoshis and Bitcoin Units
One bitcoin equals 100,000,000 satoshis — the same relationship a dollar has to a hundred cents, just scaled up a millionfold. This deep divisibility is deliberate: it lets Bitcoin handle a $50,000 transfer and a few-cent tip using the same units. At a $60,000 BTC price, 100,000 sats is worth about $60, and a single sat is worth roughly $0.0006.
Denominating in sats has become common as Bitcoin's price has climbed. It feels more natural to “stack 500,000 sats” than to say “0.005 BTC,” and it makes the idea of owning a fraction of a bitcoin far less intimidating. Whether you think in sats, whole coins, or dollars, this converter keeps all three in sync so you always know what an amount is worth.
Good to Know
100 million to one
1 BTC = 100,000,000 sats. Keep the powers of ten straight: 1,000 sats is 0.00001 BTC, and 1 million sats is 0.01 BTC.
Sats make small buys clear
Recurring buys and tips are easier to reason about in sats. “Stacking sats” simply means accumulating Bitcoin in small amounts over time.
Use your own price
Edit the BTC price field to check what an amount was worth at a past price or on a specific exchange.
Lightning uses sats
Bitcoin's Lightning Network denominates payments in sats (and even millisats), so getting comfortable with the unit helps for fast, low-value transfers.
Dollar value moves
A fixed number of sats is a fixed amount of Bitcoin, but its dollar value changes every second with the market price.
Not the smallest forever
The satoshi is the smallest on-chain unit today; layers like Lightning can split a sat into thousandths (millisats) for tiny payments.
Frequently Asked Questions
What is a satoshi?
A satoshi, or "sat," is the smallest unit of Bitcoin. One bitcoin is divisible into 100,000,000 satoshis. It is named after Satoshi Nakamoto, Bitcoin's pseudonymous creator. Because a whole bitcoin is expensive, sats make it easy to talk about and transact small amounts — buying "50,000 sats" is more natural than "0.0005 BTC."
How many satoshis are in one Bitcoin?
Exactly 100,000,000 (one hundred million) satoshis make up one bitcoin. So 1 sat = 0.00000001 BTC. This eight-decimal divisibility is built into the Bitcoin protocol and is the reason Bitcoin can be used for both large and very small payments.
How much is a satoshi worth in USD?
A satoshi's dollar value is the current Bitcoin price divided by 100,000,000. If Bitcoin is $60,000, one satoshi is worth $0.0006 — about six hundredths of a cent. The converter uses a live BTC price so the sat-to-USD value updates with the market; you can also enter your own price.
Where does the Bitcoin price come from?
The live price is fetched from a public market API when the page loads. You can override it by typing any price into the BTC price field — useful for checking historical values or a specific exchange's price. If the live price is unavailable, just enter one manually.
Why do people count in sats?
As Bitcoin's price has risen, whole coins have become expensive, so the community increasingly denominates smaller amounts in sats. It also makes Bitcoin feel more accessible — you do not need to buy a whole coin, and "stacking sats" has become shorthand for accumulating Bitcoin a little at a time.
