What is Bitcoin Unit Converter?
Bitcoin Unit Converter helps you convert between different denominations of Bitcoin (BTC). The smallest unit is a Satoshi (sat), named after Bitcoin's creator, Satoshi Nakamoto. This tool supports all common Bitcoin units and provides fiat currency conversion for practical value estimation.
1 Bitcoin = 100,000,000 Satoshis. Understanding these units is essential for Bitcoin transactions, fee calculations, and price analysis.
Bitcoin Units Explained
| Unit | Value in Satoshis | Common Use |
|---|---|---|
| Satoshi (sat) | 1 | Smallest unit, transaction fees |
| Microbitcoin (μBTC / bits) | 100 | Small payments, tipping |
| Millibitcoin (mBTC) | 100,000 | Medium transactions |
| Centibitcoin (cBTC) | 1,000,000 | Larger payments |
| Decibitcoin (dBTC) | 10,000,000 | Rare, large amounts |
| Bitcoin (BTC) | 100,000,000 | Main currency unit |
What is a Satoshi?
A Satoshi (sat) is the smallest unit of Bitcoin, named after Bitcoin's pseudonymous creator, Satoshi Nakamoto. 1 Bitcoin = 100,000,000 Satoshis (10⁸). Satoshis are commonly used for expressing small amounts, transaction fees, and Lightning Network payments.
What are bits (μBTC)?
Bits, also known as microbitcoin (μBTC), represent 100 satoshis or 0.000001 BTC. This unit became popular as a more user-friendly denomination than satoshis for small payments and tipping, especially in gaming and microtransaction contexts.
What is mBTC (millibitcoin)?
mBTC (millibitcoin) equals 0.001 Bitcoin or 100,000 satoshis. It's commonly used in exchanges, wallets, and commerce for medium-sized transactions, providing a practical middle ground between satoshis and full bitcoins.
Why are there so many Bitcoin units?
Multiple denominations exist to make Bitcoin more practical across different value ranges. As Bitcoin's price increased, smaller units like satoshis and bits became necessary for everyday transactions. Different units serve different purposes: satoshis for fees and micro-payments, mBTC for medium transactions, and BTC for large holdings.
How do I calculate Bitcoin transaction fees?
Bitcoin transaction fees are typically calculated in satoshis per byte (sat/vB) or satoshis per virtual byte. Multiply the fee rate by your transaction size to get the total fee. For example: 300 vBytes × 50 sat/vB = 15,000 sats = 0.00015 BTC.
What's the difference between Bitcoin units and fiat conversion?
Bitcoin units (BTC, mBTC, sat, etc.) are different denominations of the same cryptocurrency, like dollars and cents. Fiat conversion translates Bitcoin's value into traditional currencies (USD, EUR, etc.) based on current market exchange rates, which fluctuate constantly.
Common Conversion Examples
- 1 BTC = 100,000,000 satoshis
- 1 BTC = 1,000 mBTC (millibitcoin)
- 1 BTC = 1,000,000 bits (microbitcoin)
- 10,000 satoshis = 0.0001 BTC = 0.1 mBTC
- 1 mBTC = 100,000 satoshis = 1,000 bits
- Transaction fee: 5,000 sats = 0.00005 BTC = 0.05 mBTC
- Lightning payment: 1,000 sats = 10,000 millisats
