▪ Understanding Bitcoin Units

Bitcoin, satoshis, and why units matter

Every Bitcoin is divisible into 100 million smaller units called satoshis (sats). Think of it like dollars and cents — except Bitcoin has eight decimal places instead of two. As Bitcoin's price rises, people increasingly price things in sats rather than whole coins. A coffee might cost 5,000 sats instead of 0.00005 BTC. This converter lets you move between all three units instantly, using the current market price for USD conversions.

▪ Common Questions
How many satoshis are in one Bitcoin?

Exactly 100,000,000 (one hundred million). This is hardcoded into the Bitcoin protocol and will never change. It means even a small fraction of a Bitcoin can be expressed as a whole number of sats.

Why do people use satoshis instead of Bitcoin?

As Bitcoin's price has risen, most everyday amounts involve tiny fractions of a coin. Saying "50,000 sats" is easier to understand than "0.0005 BTC". Satoshis make Bitcoin feel more accessible and practical for daily use.

Is the USD conversion based on real-time prices?

Yes. This converter fetches a live Bitcoin price that refreshes every 60 seconds. The USD values reflect the current market rate at the time of conversion.

What's the smallest amount of Bitcoin I can send?

On the Bitcoin base layer, the practical minimum is around 546 sats (the "dust limit"). On the Lightning Network, you can send as little as 1 sat. The protocol itself supports down to 1 satoshi.
