Converting from old money/new money to euro

Would anybody have a formula for converting old money (pounds, shillings and pence) into new money and then into euros.

There's no macro on their site but useful information and they may be able to tell you where to find one:

Central Bank:

By "old money" do you mean pre-decimalisation LSD?
When doing this conversion do you mean to account for inflation?
Is this just of academic interest or do you actually have LSD that you want to exchange for € (is that - as opposed to changing punts - possible?!)?
In nominal terms wasn't an old Irish pound just exchanged for a new post-decimalisation punt?

That's right. It's just the change from 240 d's to 100 p's was all that I needed clarified. Got the answer from here:
