TxTool

crypto.txtool

This extension allows you to get an accurate estimation of the value of any transaction on etherscan.io in many currencies. Etherscan displays an estimation based on daily Ether price while this extension uses minute Ether price for transactions less than 7 days old and hourly Ether price otherwise, making it more precise. You can obtain an estimation in many currencies such as AED (United Arab Emirates Dirham), BTC (Bitcoin), GBP (British Pound) and USD (United States Dollar). Note: The extension doesn't work on pending transactions since the value of a transaction fee is finalized after the transaction itself is processed.
