My only concern is how this is a different method compared to portfolio.

In portfolio we are using Ethers+BigNumber.js so little conversion loss.
But extension may have some formatting.

... we can deal with this in the future lolol

const numericAmount = parseFloat(`${amountInEther}`) * parseFloat(usd);

return formatAmount(numericAmount);
};
