That's not quite what I meant to highlight. GURB has a pair of articles that reverse engineer UT's formulas for HE, HEAT (penetrating and linked blasts) and HEDP/MP relative to warhead diameter pretty accurately:
>Wd is the warheads diameter in millimeters. TL is 2.1 at TL9, 2.4 at TL10, 2.7 at TL11 and 3 at TL12. Wt is 1 if the warhead is standard HEAT, 1.5 if HEDP.
>Dice of Damage = (Wd × 0.26 × TL) / Wt
>Linked Explosion Dice = Wd^(3 / 2) × Wt
>Fragmentation Dice = Wd / 20
A later article has the following formulas:
>Ww = Wd^3 × 0.000002
>HE/HEC Dice of Damage = sqrt(Ww) × 74.2 / 3.5
>HEAT/HEMP Dice of Damage = Ww × 2.2 / 3.5 or Ww × 2.5 / 3.5 for HEMP
>HEAT/HEMP Linked Explosion Dice = sqrt(Ww) × 39.6 / 3.5

This is a good starting point, there's plenty of constants that can be tweaked to reflect lower tech levels, it's just a question of taking known damage values and extracting the TL factor. To be clear, respectively the constants I was calculating as variables for would be TL in the first formula, Wt in the second, 0.85 in the fourth, 2.2 and 2.5 in the fifth, and 39.6 in the sixth.
As you can see from pic related, the formulas don't fit at all for HT, and aren't useful to design examples that don't have a basis in reality as a result. The columns are, respectively and solving for the variable labeled TL:
>(Wd × 0.26 × TL) / Wt
>Wd^(3 / 2) × TL (for linked blasts)
>sqrt(Wd^3 × 0.000002) × TL / 3.5
>Wd^3 × 0.000002 × TL / 3.5
Note the first column does include the 1.5 for HEDP.
