Crypto Unit Converter
Free Crypto Unit Converter. Convert denomination units for BTC, ETH, SOL, and USDT including satoshi, gwei, lamport, and micro units.
This converter uses denomination math only and does not fetch market prices. It converts units of the same asset.
How to use Crypto Unit Converter
The Crypto Unit Converter handles conversions between all common cryptocurrency denominations for multiple blockchain networks simultaneously. It covers Bitcoin denomination units (BTC, mBTC, μBTC, satoshi), Ethereum units (ETH, gwei, wei), and common ERC-20 token decimal conversions — all in one place.
Use it when working with raw blockchain data, reading smart contract values, or verifying wallet amounts. Smart contracts store token amounts in their smallest denomination (wei for ETH, base units for ERC-20 tokens) — the converter translates these raw numbers into human-readable amounts and back again for debugging contract interactions.
Input guide and assumptions
Select the blockchain network (Bitcoin, Ethereum, or a specific ERC-20 token), then enter a value in any denomination. For ERC-20 tokens, the decimal precision varies by contract — most tokens use 18 decimals like ETH, but USDC and USDT use 6 decimals, and some tokens use non-standard values. Enter the token's decimal count in the custom decimals field.
The raw value field shows the integer representation used by the blockchain (e.g., 1 ETH = 1,000,000,000,000,000,000 wei). This is critical for smart contract interactions where the input must be in base units. The human-readable field shows the decimal-formatted value as displayed in wallets and exchanges.
How to interpret results correctly
Cryptocurrency unit conversions reveal the underlying scale of blockchain systems and help contextualize value transfers across drastically different denominations. When you see 0.00001 BTC, converting to satoshis (1,000 sats) makes the quantity immediately tangible. When evaluating Ethereum gas costs in gwei, converting to USD at current ETH price transforms abstract technical metrics into economic reality. The ability to fluidly convert between denominations is essential for comparing value across networks: 1 MATIC at $0.80 vs. 1 SOL at $150 vs. 1 ETH at $2,300 require common units to enable meaningful comparison of transaction cost efficiency.
Denomination differences create persistent confusion for new crypto participants. Bitcoin's 8-decimal precision (1 BTC = 100,000,000 satoshis) enables microtransactions at the satoshi level while maintaining the psychological significance of whole-BTC milestones. Ethereum's 18-decimal precision (1 ETH = 10^18 wei) serves different technical purposes — gas calculations require granular unit precision to properly price computational resources. Understanding why each network chose its denomination structure provides insight into the network's design philosophy and intended use cases.
Common mistakes to avoid
- Conflating different token units when comparing 'amounts.' Saying '1 ETH worth of tokens' means dramatically different things depending on whether you're discussing WETH, ETH2, stETH, or rETH — all of which may have slightly different values. Similarly, '1 BTC' on different chains (WBTC on Ethereum, BTC on Bitcoin, renBTC on various chains) may have fractional price discrepancies due to minting/redemption dynamics. Always specify the exact token contract when precision matters.
- Using stale conversion rates for financial calculations. In a market that moves 5%–10% daily, a rate from even 4 hours ago can be meaningfully inaccurate. For tax calculations, always use the market price at the exact transaction timestamp. For investment decisions, use real-time rates from reliable oracles. Never use memory or approximation for conversion rates in any financial context.
