About this app

WHAT IT DOES

Ether Converter is a simple yet powerful tool for converting between Ethereum denominations. Enter an amount in Ether, optionally provide a USD price, and the tool instantly converts to Wei, Gwei, and USD (if price is provided). It displays the results in a clean grid format showing Ether, Gwei, Wei, and USD value. Quick buttons for 1 ETH and 1 Wei allow fast testing. This is essential for developers working with Ethereum transactions, users understanding gas costs, or anyone needing to convert between Ether units.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Enter the amount in Ether in the input field. Optionally, enter a USD price per Ether to see the fiat value. Click "Convert" to perform the conversion. The tool displays the input amount in Ether, the USD value (if price was provided), and a grid showing the converted values in Ether, Gwei, Wei, and USD (if price was provided). Use the quick buttons: "1 ETH" to set the amount to exactly 1 Ether, or "1 Wei" to set the amount to the smallest unit (0.000000000000000001 ETH). This is useful for quickly testing conversions without manual input.

TECHNICAL MECHANISM

The tool uses ethers.js utilities for precise conversion. It parses the input as an Ether amount using ethers.utils.parseEther() to convert to Wei (the smallest unit). It then divides by 10^9 to get Gwei. The Ether value is displayed with 6 decimal places for readability. If a USD price is provided, it multiplies the Ether amount by the price to get the USD value. The tool uses BigNumber arithmetic internally to maintain precision and avoid floating-point errors. The conversions are: 1 ETH = 10^18 Wei, 1 ETH = 10^9 Gwei. The Wei value is displayed as a full integer string, Gwei as an integer, and Ether with 6 decimal places. All operations are performed client-side — no data is stored or transmitted. The tool is read-only and does not sign any transactions.

WHAT IT CANNOT SEE

The tool cannot fetch real-time exchange rates without external price feed or API — the USD price must be entered manually. It cannot convert between non-EVM denominations (e.g., SOL, BTC) — only Ether, Gwei, Wei, and USD are supported. It cannot provide historical conversion rates — the tool only uses the current input. It cannot handle gas price conversions without additional data — gas prices are not converted. It cannot convert units for tokens with different decimals without additional configuration — the tool is designed for Ether only. It cannot automatically detect the current ETH price. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the conversion itself is chain-agnostic. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the conversion works regardless. The tool uses BigNumber for precision — no floating-point errors. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify conversions with official sources when dealing with real funds.
