Understanding Bitcoin Units
Bitcoin is divisible to eight decimal places, making it far more divisible than any traditional currency. The smallest unit, a satoshi (named after Bitcoin's creator), represents 0.00000001 BTC.
As Bitcoin's price has risen, most people interact with fractions of a Bitcoin rather than whole coins. The Bitcoin community increasingly uses satoshis as the standard unit for everyday transactions, especially on the Lightning Network.
When you see prices on exchanges or in wallet apps, they might display in BTC, sats, or mBTC depending on the platform. This converter helps you quickly translate between all of them.
Frequently Asked Questions
How many satoshis are in one Bitcoin?
One Bitcoin (BTC) equals exactly 100,000,000 satoshis (sats). A satoshi is the smallest unit of Bitcoin on the main blockchain.
What is mBTC?
mBTC (millibitcoin) is one-thousandth of a Bitcoin, or 0.001 BTC. It equals 100,000 satoshis. Some wallets and exchanges display amounts in mBTC for readability.
Why do people use satoshis instead of BTC?
As Bitcoin's price has grown, most everyday transactions involve tiny fractions of a BTC. Saying '50,000 sats' is more intuitive than '0.0005 BTC'. The Lightning Network primarily uses satoshis.
