pivx calculator

I suggest a simple conversion calculator. For quick calculations in commerce.
One more tool never hurts. https://toolbox.pivx.org
in MPW it already calculates automatically according to the pre-defined currency. However, I believe it makes having a calculator easier for many other situations.

Example:

Something similar to this on the main page would be interesting.

Example:

https://app.mypivxwallet.org/?pay=DThrYnqrGg6LoySUeR3r5jxb6r3LMMHLWN&amount=100&desc=PIZZA%20DAY

In this example I would like to pass the direct value as a parameter, so that the amount of PIV is calculated automatically.
How would it be?
"amountCurrency" It does not work
