Comparison between Mongoose Traveller, Classic Traveller, TNE, etc. armor type

[Mad Russian]

Has anyone written up a comparison of armor values for the above mentioned versions of Traveller?
This might be helpful in translating different continuing characters' spacecraft from several versions of rules used in campaigns over the years to a unified campaign that I am working on currently.

Mad Geo did up through T4.

Let's see, using N as rating, and H as tonnage of hull:
CT Bk 2: No armor.
CT Bk 5, T20: linear + base, using N+NH/100 tons per AV
MT, Striker: thickness in mm is looked up to find AV; Striker provides an official conversion that fails the tonnage match test. (HGAV+65=SAV)
TNE, T4: Thickness in mm is converted to AV; both use the exact same formulae.
MGT: Linear only TlfactorNH/20, where Tlfactor is 2,4,or 6.

However, we can convert CT to MGT directly, due to the same range: 0 to TL each.

Thank you for your response. I have begun doing some conversions, and it is the easiest to convert from High Guard CT to Mongoose Traveller (mgT).

However, if I have a TL12 mgT ship with Crystaliron armor in one layer requiring 5% of Hull tonnage (AF 4), that same ship with AF4 in CT (@5%Hull) would require the ship to be at TL14+ (see CT High Guard, p23).
