How to Convert Crypto Units

01Choose asset & unitsSelect BTC or ETH from the asset dropdown, then pick the source unit (e.g. BTC) and target unit (e.g. satoshi). The dropdowns automatically adjust to valid pairs — BTC supports BTC ↔ satoshi, ETH supports ETH ↔ gwei ↔ wei.

02Enter the amountType any decimal value into the amount field. The converter uses exact BigInt integer arithmetic internally, so results are always precise — no floating-point rounding errors, even for very small fractions like 0.00000001 BTC.

03Copy or swapCopy the converted result to your clipboard for use in wallets, block explorers, or spreadsheets. Tap the swap button to instantly reverse the from/to units and re-convert in the opposite direction.

Privacy & Security

This tool runs entirely in your browser using local BigInt math. No inputs are ever sent to our servers — your data stays private. Works offline once loaded.

About Crypto Unit Converter

Crypto Unit Converter helps you convert between common blockchain denominations without floating-point rounding errors. It supports BTC ↔ satoshi and ETH ↔ gwei ↔ wei conversions using exact integer arithmetic (BigInt) under the hood. Each unit represents a different power of 10: 1 BTC = 10⁸ satoshi, 1 ETH = 10⁹ gwei = 10¹⁸ wei. The converter scales between these by multiplying or dividing by the appropriate power of 10, ensuring zero precision loss.

When to use it

Use this when reading block explorer values (which often show sat/wei amounts), calculating gas fees in gwei, or working with wallet balances where different units are displayed. Essential for developers building transactions, DeFi users comparing gas costs, and anyone verifying on-chain data.

Tips & Tricks

•1 BTC = 100,000,000 satoshi (10⁸). 1 ETH = 1,000,000,000 gwei (10⁹) = 1,000,000,000,000,000,000 wei (10¹⁸).
•Gas fees are quoted in gwei — a 21,000 gas transfer at 30 gwei costs 0.00063 ETH (21,000 × 30 × 10⁻⁹).
•Confusing gwei with wei is a common mistake — always double-check the unit. 1 gwei = 1,000,000,000 wei.
•This tool works offline once loaded; no network connection is needed for conversions.
•Use sat or wei for integer-precise values when building transactions programmatically — avoids floating-point issues.
