Why start in sats

Faucets, Lightning invoices, and tip bots quote satoshis. Entering “2032 sats” is clearer than 0.00002032 BTC. This page defaults to sats so micro amounts stay readable.

Fixed scale, live dollars

1 BTC always equals 100,000,000 sats. The USD column multiplies your BTC-equivalent by live spot. If the feed is slow, unit conversion still works.

Micro-earnings context

When claim sizes are tiny, convert to USD to decide whether a withdrawal fee eats the stack. Pair this with the fee calculator before you push on-chain.

Sources & methodology

Factual claims cite primary documentation. Interpretation and calculator assumptions are labeled separately so you can verify the source yourself.

Source: Bitcoin Developer Documentation — Satoshis are the smallest commonly quoted Bitcoin sub-unit (1e-8 BTC).
GetFreeBit analysis: This page defaults to sats because faucets and Lightning invoices usually quote sats, not eight-decimal BTC strings.
Source: Lightning Network documentation — Lightning amounts are typically denominated in millisatoshi or satoshi units on invoices.
GetFreeBit analysis: Unit conversion here does not estimate routing fees or channel liquidity—only sats ↔ BTC ↔ USD math.

Examples

Turn 50,000 faucet sats into BTC and a USD snapshot.
Check whether 10,000 sats covers a typical on-chain fee today.
