Understanding Bitcoin Units

Bitcoin works just like dollars and cents. Just as 1 dollar = 100 cents, in Bitcoin: 1 BTC = 100,000,000 satoshis.

A satoshi (sat) is the smallest unit of Bitcoin, named after Bitcoin's creator, Satoshi Nakamoto. Think of sats as the "pennies" of Bitcoin.

Since Bitcoin can be worth a lot in dollars, most people don't need to buy a whole Bitcoin. You can buy any fraction you want—even just a few thousand satoshis to start. Try the converter below to see how different amounts compare!

Key Takeaways

  • You don't need to buy a whole Bitcoin. Bitcoin is divisible into 100 million pieces. You can start with any amount.
  • Satoshis (sats) are like cents. Just as $1 = 100 cents, 1 BTC = 100,000,000 sats. They're named after Bitcoin's creator.
  • Why different units? As Bitcoin's price rises, smaller units make everyday purchases easier. Would you rather pay "0.00001 BTC" or "1,000 sats" for coffee?
  • Other units exist too: mBTC (1 thousand sats) and bits (100 sats) are helpful middle denominations, though less common.
  • Always double-check amounts! Bitcoin transactions can't be reversed. Make sure you're sending the right amount in the right unit.
  • Thinking in sats helps. Many Bitcoiners prefer sats because they feel more natural for small purchases, just like using cents instead of fractions of a dollar.
