About this app
WHAT IT DOES
Convert Wei to Ether enables you to convert between Ethereum's denominations: wei (the smallest unit), gwei (1e9 wei), and ether (1e18 wei). Ethereum uses these denominations for gas pricing, transaction values, and balances. The tool takes a value in any of these units and displays the equivalent in all three denominations, with proper formatting and precision. This is essential for developers, users, and anyone working with Ethereum transactions who needs to understand the relationship between different unit scales. The tool handles large numbers using ethers.js BigNumber, ensuring accuracy even for very large values. It provides clear results showing the conversion in each denomination.
HOW TO USE
Connect your wallet using the BGWallet connector (required for context). Select the input format: "Wei" for the smallest unit, "Gwei" for gas pricing, or "Ether" for the standard unit. Enter the value in the input field. Click "Convert" to compute the equivalent values. The tool displays the input value, the value in wei, gwei, and ether, with proper formatting. You can copy the results to your clipboard for further use. The tool provides real-time validation and error handling for invalid inputs.
TECHNICAL MECHANISM
This tool implements Ethereum denomination conversion using ethers.js BigNumber for precise arithmetic. The conversion factors are: 1 ether = 10^9 gwei = 10^18 wei. The tool accepts input in any of the three denominations and converts to the other two using these factors. For wei input, the value is treated as a BigNumber and divided by 10^9 for gwei and 10^18 for ether. For gwei input, the value is multiplied by 10^9 for wei and divided by 10^9 for ether. For ether input, the value is parsed using ethers.js parseEther to handle decimal precision, then converted to wei and gwei. The tool uses the ethers.js formatUnits function to display values with appropriate decimal places. All arithmetic is performed using BigNumber to avoid precision loss with large numbers. The conversion is performed locally in the browser with no data sent to external servers.
WHAT IT CANNOT SEE
This tool cannot verify that the value corresponds to an actual on-chain balance or transaction—it only performs unit conversion. It does not support conversion between other denominations beyond wei, gwei, and ether. The tool cannot handle extremely large numbers beyond JavaScript's safe integer limit without using BigInt; however, ethers.js BigNumber provides arbitrary precision. It does not support automated fetching of wallet balance for conversion; the user must input the value manually. The tool cannot verify the conversion accuracy for decimal values beyond standard precision; it uses the standard 18 decimal places for ether. It does not support batch conversion of multiple values simultaneously; each conversion must be performed individually.
PLEASE NOTE
This tool is designed for developers and users working with Ethereum units. Wei is the smallest unit and is used for precise gas calculations. Gwei is commonly used for gas prices (e.g., 10 gwei). Ether is the standard currency unit. The tool uses ethers.js for precise conversions and supports very large numbers. The conversion is performed locally in the browser and is never transmitted to external servers. The tool is read-only and does not require any on-chain interactions. Always verify the conversion results before using them in transactions or smart contracts. The tool is intended for testing, development, and educational purposes.
