Bitcoin, satoshis, and why units matter
Every Bitcoin breaks down into 100 million smaller units called satoshis (sats). It works like dollars and cents, but with eight decimal places instead of two. Because one whole Bitcoin costs tens of thousands of dollars, you'll usually deal in fractions. A coffee might run 5,000 sats rather than 0.00005 BTC. Both mean the same thing. The converter above uses the current market price, refreshed every 60 seconds, for the USD column.
Exactly 100,000,000 (one hundred million). The Bitcoin protocol hardcodes that number, and no update can change it. So even a tiny fraction of a Bitcoin maps to a whole number of sats.
Most everyday amounts are tiny fractions of a coin. "50,000 sats" is quicker to read and harder to miscount than "0.0005 BTC." Whole numbers are just easier to work with.
Yes. The converter pulls a live Bitcoin price and refreshes it every 60 seconds. Your USD values reflect the market rate at the moment you type.
On the base layer, the practical floor is about 546 sats (the "dust limit"). On the Lightning Network, you can send as little as 1 sat.
