There are exactly 100,000,000 satoshis in one Bitcoin. That's one hundred million, or 10 to the power of 8. Written out: 1 BTC = 100,000,000 sats.
If that number seems oddly specific, it is. Satoshi Nakamoto chose it deliberately when designing Bitcoin's monetary system. The goal was to make Bitcoin divisible enough to remain useful as a medium of exchange even if the price of a single coin climbed into the hundreds of thousands. That foresight has proven correct.

A satoshi, commonly shortened to "sat," is the smallest unit of Bitcoin that can be recorded on the blockchain. One satoshi equals 0.00000001 BTC. Think of it the way you think of cents to a dollar, except there are 100 million of them per coin, not 100.
The unit is named after Bitcoin's anonymous creator, Satoshi Nakamoto. Whether Nakamoto is a single person or a group remains unknown, but the denomination named in their honor now underpins the entire Bitcoin economy, from Lightning Network micropayments to on-chain transaction fees.
The fiat value of a satoshi moves with Bitcoin's price. There is no fixed rate. At a BTC price of $100,000, one satoshi is worth $0.001, or one tenth of a cent. At $50,000 per BTC, one sat is worth $0.0005.
The table below shows approximate satoshi equivalents at different BTC price levels:
| BTC price | Value of 1 sat | Sats per $1 |
|---|---|---|
| $50,000 | $0.00050 | ~2,000 |
| $75,000 | $0.00075 | ~1,333 |
| $100,000 | $0.00100 | ~1,000 |
| $150,000 | $0.00150 | ~667 |

Bitcoin's divisibility is a design choice, not an accident. Nakamoto wanted Bitcoin to function both as a store of value and as a practical medium of exchange. A coin worth tens of thousands of dollars is useless for buying a coffee if it cannot be divided small enough. The 8-decimal structure solves that.
The rule is hardcoded into Bitcoin's protocol and enforced by every node on the network. It cannot be changed without a consensus upgrade that the community has never had reason to pursue, and likely never will.
One consequence: because all amounts in the Bitcoin codebase are stored as integers in satoshis, the blockchain never deals in fractions at all. "0.001 BTC" is just a human-readable label for 100,000 satoshis.
Satoshis are the most widely used sub-unit of Bitcoin, but several others exist:
| Unit | Symbol | BTC equivalent | Satoshis |
|---|---|---|---|
| Bitcoin | BTC | 1 | 100,000,000 |
| millibitcoin | mBTC | 0.001 | 100,000 |
| microbitcoin (bit) | uBTC | 0.000001 | 100 |
| finney | – | 0.0000001 | 10 |
| satoshi | sat | 0.00000001 | 1 |
In practice, only BTC, mBTC, and sats see meaningful usage. Most modern wallets let you toggle between BTC and sat displays.
Bitcoin's total supply is capped at 21 million BTC. Multiply that by 100 million satoshis per coin and you get 2.1 quadrillion satoshis, or 2,100,000,000,000,000 sats, as the absolute maximum that will ever exist.
This hard cap is enforced by Bitcoin's code and backed by the network's consensus rules. No government, company, or individual can increase it. It is what makes Bitcoin genuinely scarce at the unit level, even as each coin remains divisible into 100 million pieces.
Curious how many bitcoins are left to mine before that cap is hit? The countdown is already well underway.
The Lightning Network is Bitcoin's second-layer payment protocol, designed for fast, cheap transactions that settle off-chain before being batched onto the main blockchain. It runs entirely in satoshis.
Transaction fees on Lightning are typically measured in millisatoshis, one thousandth of a satoshi. This is currently theoretical in terms of settlement, since the main chain only records whole satoshis, but it shows how the system was built to accommodate even finer denominations at higher layers.
Common Lightning use cases where sats matter: tipping content creators, micropayments for API calls, gaming rewards, and streaming money by the second.
As Bitcoin's price has risen, accumulating a whole coin has moved out of reach for most people. The community's answer was the "stack sats" mindset: buy small amounts regularly, let them compound, and focus on satoshi accumulation rather than whole-coin ownership.
Dollar-cost averaging in sats instead of BTC is functionally identical in terms of market exposure, but it reframes the mental model. Buying $10 of Bitcoin a week is buying roughly 7,000 to 10,000 sats per week at current prices. Over years, that adds up — and if you're new to all of this, our bitcoin-basics guide covers the fundamentals in plain language.
The math is straightforward:
Examples:
Most crypto wallets handle this conversion automatically, displaying balances in whichever unit you prefer.
If you want to pay with Bitcoin in the real world, Oobit lets you pay in store, with tap to pay, or online at any Visa-accepting merchant globally. No need to convert to fiat in advance. Your crypto, including amounts measured in sats, is converted at the point of sale. It works with self-custody, meaning your keys stay yours until the moment you spend.
