How This Tool Works

This converter uses the exact Bitcoin denomination hierarchy defined in the Bitcoin protocol.

1 BTC = 1,000 mBTC = 1,000,000 μBTC = 100,000,000 satoshis
USD Value = BTC Amount × Current Price
Satoshis = BTC Amount × 100,000,000

Enter any field and all other denominations update in real-time. The quick-reference table shows the USD value of common BTC amounts at your entered price. All conversions are exact integer arithmetic — no floating-point errors — matching how the Bitcoin protocol itself processes transactions.
