These will allow you to convert ships from Ships of the Star Fleet Manuals by Todd Guenther and Eric Kristianson, and import them into FASA's STCS and ADB's SFB.
Crew Conversion
Crew are unchanged for FASA, SFB has them divided by 10 for Crew Units (8 for Gorn)
Marines are unchanged for FASA, SFB has them divided by 10, plus 10 (Federation), 14 (Klingon and Gorn), 12 (most other races)
For ships with Fighters, add 1 Deck Crew per 2 Fighters
Durability Conversion
For Hull, treat the Constitution and Enterprise-Class CAs as 1.0, with 20 Superstructure for Constitution, and 26 for Enterprise, and give both ships 16/20 Hull Boxes in SFB, and view smaller/larger ships as being anywhere from 0.5 to 1.5 times this, with ships of the Excelsior and Ambassador generations going as high as 2.0-3.0, and TNG ships going up to 4.0, 5.0 in the case of some 4X monstrosities.
For Shields, consult the Chart below and apply the results to the ship
0Xe- FSG (1/1) (9) OR 24/18/18/18/18/18

4Xe- FXSB (1/7) (60) OR 200/200/200/200/200
Shuttle Conversion
The Shuttles are unchanged for FASA, SFB has them divided in half, and remove some of the specialty shuttles, and represent the others with normal SFB Type (GAS, MRS, HTS, MSS).
Transporter/Tractor Conversion
Unchanged for FASA, for SFB, 2 Personnel Transporters, 2.5 Combat Transporters, 2 Small Cargo, 1 Large Cargo, and 4 Emergency Transporters each equal 1 Tran Box.
Constitution/Enterprise CAs and most smaller ships get 2 Trac Boxes, bigger ships get 3-6 Trac Boxes.
