Conversion price Convertible Bond

Hi!
If a bond is issued at $800 with a face value of $1000 and trades at $700.
What would be the conversion price?

From what I find in the forum we usually say conversion price = par/conversion ratio.

Here

I find that they divide the issue price (not the face value) by the conversion ratio.

Could you tell me what is correct?

You have your formula

conversion price = par/conversion ratio.

You have par valeu =- face vaue = $1000

But you have not givena conversion ratio - the number of shares you can covert each bond into.
