Hi @HelloFeture!

I just checked and you are right, there is a difference between web3.js and using https://eth-converter.com/ in the first function toWei(), i'll ping the team to investigate this asap!

// import web3 module
import { Web3 } from "web3";

const web3 = new Web3("https://rpc2.sepolia.org");

const firstConversion = web3.utils.toWei("0.0033086855466118933", "ether"); //ether to wei
console.log(firstConversion);
//33086855466118933 => web3.js
//3308685546611893   => eth-converter
