No fees, spread, or slippage are included.
Multiply BTC by 100,000,000
BTC amount × 100,000,000 = satoshis
SATS precision
The result is shown as whole satoshis because one sat is the smallest standard Bitcoin unit.
Direction matters
This direction starts with a decimal bitcoin balance and turns it into a whole-number satoshi count. It is useful when a wallet, fee, or Lightning invoice is easier to understand in smaller units.
How to convert BTC to SATS
Enter a Bitcoin amount above. The calculator translates it through the relevant public reference and displays an indicative amount in Satoshis. You can reverse the direction without leaving the page.
One BTC always equals 100,000,000 satoshis. No market price is needed for this denomination conversion.
A fixed Bitcoin denomination
This conversion uses the protocol unit relationship only: one BTC equals 100,000,000 sats. No exchange, order book, fiat rate or stablecoin is needed, so the result changes only when the entered amount changes.
About Bitcoin
Bitcoin is the native unit of the Bitcoin network. One BTC can be divided into 100,000,000 satoshis, and control depends on the keys required to spend its transaction outputs.
BTC is used to measure bitcoin balances, transaction outputs, fees and market prices. The protocol's issuance schedule is separate from the exchange rate shown by a venue. For a reproducible Bitcoin value, retain the BTC quantity, price pair, venue or index method, timestamp, and quote asset. A wallet balance and an exchange balance also have different custody evidence, even when both are written in BTC.
About Satoshis
A satoshi, commonly shortened to sat, is the smallest standard Bitcoin unit. One sat equals 0.00000001 BTC and 100,000,000 sats equal one BTC.
Sats make small payments, Lightning invoices and fee amounts easier to read without writing many leading zeros. When a source displays sats, preserve the integer count before converting it to BTC. This avoids losing scale through rounded decimals and makes Lightning invoices, on-chain fees, and small wallet balances easier to compare with their original record.
When this conversion is useful
- Reading lightning invoices and small payments
- Checking wallet balances without leading zeros
- Learning bitcoin's fixed unit structure
The page answers a unit question only. It cannot decide whether either asset, venue, custody method or transaction is suitable for a reader.
Risks the number does not show
BTC: BTC has no central price and can move sharply. A conversion says nothing about custody, transaction finality, taxes or whether a purchase suits a reader.
SATS: A sat is a denomination, not a different token. Anyone offering a separate 'satoshi coin' may be using confusing or misleading language.
Spread, order-book depth, slippage, funding charges, withdrawal fees and taxes remain outside the calculation.

BTC to SATS questions
How is the BTC to SATS rate calculated?
Translate bitcoin into satoshis using Bitcoin's fixed unit relationship.
What is the main difference between BTC and SATS?
Bitcoin is the native unit of the Bitcoin network. One BTC can be divided into 100,000,000 satoshis, and control depends on the keys required to spend its transaction outputs. A satoshi, commonly shortened to sat, is the smallest standard Bitcoin unit. One sat equals 0.00000001 BTC and 100,000,000 sats equal one BTC.
What costs are excluded from this BTC-to-SATS estimate?
The BTC-to-SATS result excludes spread, trading and payment fees, slippage, withdrawal costs, taxes, and any provider minimum. Bitcoin.now cannot place or settle an order.
Why can a BTC/SATS result differ between venues?
Each venue has its own BTC/SATS order book, liquidity, spread, timestamp, and fees. The displayed public reference is therefore an estimate, not a guaranteed executable value.
How to read BTC as satoshis
This direction starts with a decimal bitcoin balance and turns it into a whole-number satoshi count. It is useful when a wallet, fee, or Lightning invoice is easier to understand in smaller units.
Keep up to eight BTC decimals
Bitcoin amounts can be written to eight decimal places. Extra decimals do not represent a smaller standard on-chain unit.
Multiply by 100 million
Move the decimal point eight places to the right. For example, 0.0025 BTC becomes 250,000 sats.
Do not apply a market price
BTC and sats are names for the same asset. The denomination result stays exact even while BTC/USD changes.
