747-400 and other Boeing aircraft Trim Question

[atc4usaf]

Hello everyone. I just had a question about the trim indicator on the Boeings: Is there a conversion anywhere that shows the relationship between degrees of trim and the units that Boeing uses?

And would those settings be similar between different aircraft, like the 737 and 747? Just wondering if Boeing kept the setting similar for transitions between aircraft.

Thanks in advance,
