Key Takeaways
- Every Bitcoin (BTC) is divisible into 100 million units (0.00000001 BTC) called satoshis, named after Bitcoin’s creator, Satoshi Nakamoto.
- Satoshis enable microtransactions, trading, and fee calculations. They’re also central to the Ordinals protocol for digital inscriptions.
- While satoshi values fluctuate with BTC’s price, the conversion rate (1 BTC = 100M sats) remains constant.
Bitcoin’s Divisibility
Bitcoin’s design as peer-to-peer electronic cash prioritizes divisibility for accessibility. Unlike fiat currencies (divisible to 0.01), BTC splits into eight decimal places (0.00000001 BTC), allowing microtransactions and flexibility as BTC’s value grows.

What Is a Satoshi?
A satoshi (sat) is BTC’s smallest unit (0.00000001 BTC), with 100 million sats per Bitcoin. The total supply of 21M BTC equals 2.1 quadrillion sats.
The Role of Satoshis
- Transactions: Facilitates small payments (e.g., tipping, microtransactions).
- Ordinals Protocol: Sats serve as carriers for digital inscriptions.
- Trading: Used in crypto pairs for low-value coins.
- Fee Calculation: Fees are denominated in sats per virtual byte (vB).
How Satoshis Relate to Bitcoin Prices
1 satoshi’s fiat value changes with BTC’s price:
- **At $100,000/BTC**: 1 sat = $0.001 (0.1 cents).
- **At $1/BTC**: 1 sat = $0.00000001.
Other Bitcoin Units
| Satoshis | Unit | BTC Equivalent |
|----------|---------------|------------------|
| 10 | finney | 0.0000001 |
| 100 | μBTC (micro) | 0.000001 |
| 100,000 | mBTC (milli) | 0.001 |
| 100M | 1 BTC | 1 |
Understanding Satoshi Value
- **$1 ≈ 9,800 sats** (at $100,000/BTC).
- 1,000 sats ≈ $0.001.
- Convert sats to fiat using tools like CoinMarketCap’s converter.
