What value should be used for scale while calculating slope percent in QGIS?

enter image description here

Some documents suggest is as 111120 and some as 365130.

I am using ESPG 4326 projection and do I need to convert this value to some other value using lat like given in this link:

The link you provided says:

scale=370400 (if elevation is in feet) or scale=111120 (if elevation is in meters)

So, what units are you using for elevation? Feet or meters?

And if you want to do this simpler, you could reproject to a CRS that uses the same units as your elevation measure.
