Rz to Ra; Surface texture conversion
Could someone please help me out with a conversion factor. I need to convert Ra to Rz. If my print states a machined surface to be controlled to a maximum of Rz125, what would be the Ra equal? My measuring equipment has parameter settings of Rz.J, Rz.I and R3z. Which setting would I want if the characteristic tolerance is Rz125? Help! Please.

Rz (din) = Ra*7.2
Rz(ISO) = Ra*7.6
