About this converter
BattleTech weapons deal fixed base damage from 2 to 20. AC/2, Flamer and Machine Gun open tied at 2, Small Laser at 3, AC/5 and Medium Laser tied at 5, Medium Pulse Laser at 6, Large Laser at 8, Large Pulse Laser at 9, PPC, AC/10 and LB 10-X tied at 10, Gauss Rifle and Clan ER PPC tied at 15 and AC/20 at 20. That makes one AC/20 equal ten AC/2s of damage. Every value here is the base per-shot figure with cluster splits left out.
How to use it
Pick two weapons and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first, one holds the matching count of the second, one holds the total in damage. Try 1 AC/20 against AC/2s.
LB-X cluster shells and missile launchers split damage across hit tables, so this table pins single-shot slug values to keep rows comparable. Inner Sphere ER PPC deals 10 against Clan 15 and stays noted per row. Heat, ammo and range brackets shape real builds beyond these bases. Mech tonnage for the same universe runs on the companion tonnage page.
