What Is a Satoshi?

A Satoshi is the smallest unit of Bitcoin — like cents to a dollar, but with eight decimal places. Understanding sats helps you think in everyday amounts instead of fractions like 0.00001 BTC.

The basics: 100 million Satoshis in one Bitcoin

One Bitcoin (BTC) equals exactly 100,000,000 Satoshis. That means 1 Satoshi = 0.00000001 BTC. The name honors Satoshi Nakamoto, Bitcoin’s pseudonymous creator.

When Bitcoin trades above tens of thousands of dollars, whole-coin prices feel abstract. Satoshis let you say “I have 500,000 sats” instead of “I have 0.005 BTC” — clearer for most people.

Why wallets and exchanges show sats

Many mobile wallets (Phoenix, Wallet of Satoshi, Strike) default to satoshi display for smaller balances. Lightning Network payments are often denominated in sats because they suit micropayments.

Satoshi vs Bitcoin — when to use each

Use BTC when discussing large holdings, portfolio allocation, or exchange listings. Use sats for tips, Lightning invoices, stacking sats, and everyday mental math.

Neither is “more correct” — they’re the same money, different scale. A good rule: if the BTC amount has more than four leading zeros after the decimal, switch to sats.

Frequently asked questions

How many Satoshis are in 1 Bitcoin?
Exactly 100,000,000 (one hundred million) Satoshis equal 1 Bitcoin.
Can you send a single Satoshi?
On-chain fees often make single-satoshi transfers impractical, but Lightning and some layer-2 systems handle tiny amounts efficiently.
How do I convert sats to dollars?
Multiply your sats by the current BTC price in USD, then divide by 100,000,000. Use our live Satoshi to USD converter for instant results.
