SPO calculated column due date hours and days

Hello,

I need to setup a Due Date calculated column on an SPO list and whilst I've managed to work out the formula for days, I cant quite work out hours?!

I have SLA priorities on my list as per the below:

5= 365 days

4= 5 days

3= 5 days

2= 1 day

1= 8 hours

=IF(Priority="5",Created+365,IF(Priority="4",Created+5,IF(Priority="3",Created+5,IF(Priority="2",Created+1,IF(Priority="1",Created+0.8)))))
