Satoshi ↔ BTC Converter

Convert between Satoshi and Bitcoin

About Satoshi ↔ BTC Converter

A Satoshi is the smallest unit of Bitcoin, named after Bitcoin's pseudonymous creator Satoshi Nakamoto. One Bitcoin equals exactly 100,000,000 (one hundred million) Satoshi. As Bitcoin's price has risen, many transactions and Lightning Network invoices are denominated in Satoshi rather than fractions of a Bitcoin, because whole numbers are easier to read and reason about.

This converter transforms Satoshi to BTC and BTC to Satoshi with full precision. It handles the 8-decimal-place arithmetic correctly so you never have to worry about rounding errors when constructing transactions, checking balances, or quoting prices.

Frequently asked questions

How many Satoshi are in 1 Bitcoin?

1 BTC = 100,000,000 Satoshi (100 million Satoshi).

Why use Satoshi instead of BTC?

As Bitcoin's price rises, everyday amounts become tiny fractions of a BTC. Satoshi makes these amounts readable — for example, 50,000 sats instead of 0.0005 BTC.

Is this useful for Lightning Network?

Yes. Lightning invoices often use millisatoshi or satoshi. This converter helps you translate between sats and BTC quickly.
