Crypto Unit Converter
Convert between sats and BTC, wei/gwei and ETH, lamports and SOL — with USD equivalents.
Formula
The smallest unit of Bitcoin is a satoshi (sat), equal to 0.00000001 BTC.
Gas prices are typically quoted in Gwei. Smart contract values use Wei.
Examples
- 0.005 BTC × 100,000,000 = 500,000 satoshis
- At $65,000/BTC: 0.005 BTC = $325
- 50 Gwei ÷ 1,000,000,000 = 0.00000005 ETH
- At $3,200/ETH: = $0.00016
- 1,000,000 ÷ 1,000,000,000 = 0.001 SOL
- At $150/SOL: = $0.15
Key Concepts
Why Satoshis?
Bitcoin is divisible to 8 decimal places. A satoshi (sat) is the smallest unit — 0.00000001 BTC. As BTC price rises, sats become a more practical unit for small transactions and Lightning payments.
Wei and Gas
Wei is Ethereum's smallest unit (10^-18 ETH). Gas prices are quoted in Gwei (10^9 Wei) for readability. When you see '30 Gwei gas', that's 0.00000003 ETH per unit of gas.
Lamports on Solana
Solana uses lamports as its base unit, named after Leslie Lamport. 1 SOL = 1 billion lamports. Transaction fees on Solana are typically 5,000 lamports (0.000005 SOL).
Stacking Sats
'Stacking sats' is the Bitcoin community term for accumulating small amounts of BTC over time. At $65K per BTC, 1 sat = $0.00065 — about $0.065 per 100 sats.
Token Decimals Vary
Not all tokens use 18 decimals like ETH. USDT uses 6 decimals, WBTC uses 8. Always check the token's decimal count when converting raw amounts.
On-Chain vs Display
Blockchains store values in their smallest unit (Wei, lamports, sats). Wallets and explorers convert to human-readable display units. Raw transaction data always shows the base unit.
Understanding Crypto Units
Each blockchain has its own denomination system. Bitcoin uses satoshis (sats), Ethereum uses Wei and Gwei, and Solana uses lamports. Understanding these conversions is essential for reading on-chain data, setting gas prices, and working with smart contracts.
The most commonly needed conversion is between the display unit (BTC, ETH, SOL) and the base unit used on-chain. Wallets handle this automatically, but developers, traders analyzing on-chain data, and anyone using block explorers need to convert manually.
This converter also shows USD equivalents using approximate prices. For live pricing, check the main Loris Tools dashboard.
Frequently Asked Questions
Are the USD prices live?
No — the USD prices are approximate defaults. Update the price field to get accurate USD conversions at current market rates.
Why do different tokens have different decimal places?
It's a design choice by each token's creator. ETH uses 18 decimals for maximum precision. USDC/USDT use 6 (like cents with extra precision). BTC uses 8 (satoshis).
What's a Finney?
A Finney is 0.001 ETH (10^15 Wei), named after Hal Finney. It's rarely used in practice — Gwei (for gas) and ETH (for value) are the standard units.
