Understand Bitcoin amounts without manually counting decimal places. Enter a value in any supported field to see its equivalent across BTC, cBTC, mBTC, bits (μBTC), finney, satoshis, and millisatoshis.
The R7 Bitcoin Units Converter also provides fiat value estimates using fetched exchange rates, making it useful for comparing payment amounts, campaign rewards, and Lightning Network denominations. Use quick actions for common amounts or copy the conversion breakdown for reference.
Bitcoin unit relationships stay fixed, while fiat values change with the exchange rate. Fiat estimates may differ from the final amounts quoted by wallets or exchanges.

Frequently Asked Questions
What is the Bitcoin Units Converter?
The Bitcoin Units Converter is a real-time mathematical calculator that converts between standard Bitcoin denominations (such as Satoshis, Millibits, and Bits) and traditional fiat currencies (such as USD and EUR). It runs 100% locally in your browser.
What are the supported Bitcoin units?
• BTC: 1 Bitcoin (1.0)
• cBTC (bitcent): 0.01 BTC (1,000,000 satoshis)
• mBTC (millibit): 0.001 BTC (100,000 satoshis)
• μBTC (bit / microbit): 0.000001 BTC (100 satoshis)
• Finney: 0.0000001 BTC (10 satoshis, honoring Hal Finney)
• Satoshi (sat): 0.00000001 BTC (1 satoshi, the smallest base on-chain unit)
• Millisatoshi (msat): 0.00000000001 BTC (1/1000th of a satoshi, used on the Lightning Network)
• cBTC (bitcent): 0.01 BTC (1,000,000 satoshis)
• mBTC (millibit): 0.001 BTC (100,000 satoshis)
• μBTC (bit / microbit): 0.000001 BTC (100 satoshis)
• Finney: 0.0000001 BTC (10 satoshis, honoring Hal Finney)
• Satoshi (sat): 0.00000001 BTC (1 satoshi, the smallest base on-chain unit)
• Millisatoshi (msat): 0.00000000001 BTC (1/1000th of a satoshi, used on the Lightning Network)
How are live fiat prices calculated?
The tool automatically fetches real-time spot rates from decentralized and public Bitcoin APIs without sending your data to any server. If offline, the converter uses cached baseline values so calculations never fail.
Why is millisatoshi (msat) only used on Lightning?
The base Bitcoin blockchain protocol only allows balances to be recorded in whole satoshis. However, the Lightning Network layer operates with sub-satoshi precision (millisatoshis) to calculate ultra-low routing fees accurately.
