General Help converting GURPS skill levels to MT

[Commander Truestar]

Hi
First, I apologize for re-asking this, because I searched and could not find it.
I want to import a GURPS device into MTU, where my skills are largely based on MT Skill rules.

What I was looking for is how to convert "First Aid-14, and 13 in Diagnosis and Physician" (from GURPS) to equivalents in the MegaTraveller "1 to 6" skill levels?

Thanks for anyone who can explain the process, so I can do it on my own in the future

Subtract the GURPS governing characteristic from the skill to get the skill level.

As there's no governing stat on a device, I'd subtract 10 and then halve it. GURPS skill-12 is basic professional competence, so it seems reasonable that this is skill-1 in MT, and GURPS' skill levels have a wider range, so halving them seems fair. Which way to round is interesting. I'd round down, but be generous about skill-0 - having any points/levels in a GURPS skill should get you skill-0. For a more general case, where you know the base stat (like for a character) replace '10' with the stat.

Thus MT skill = [GURPS skill -10] / 2

Thank you very much!
