About this converter
Three Houses swords print fixed base might from 3 to 15. Training Sword opens at 3, Iron Sword and Venin Edge tied at 5, Rapier at 7, Steel Sword, Armorslayer, Killing Edge and Wo Dao tied at 8, Levin Sword and Brave Sword tied at 9, Sword of Seiros at 11, Silver Sword at 12, Cursed Ashiya Sword, Sword of Moralta and Thunderbrand tied at 13 and Mercurius at 15. That makes one Mercurius equal five Training Swords of might. Every value here is the unupgraded base with forge bonuses left out.
How to use it
Pick two swords 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 might. Try 1 Mercurius against Training Swords.
Forging raises might along fixed tracks, for example Iron Sword 5 toward 6, so this table pins base values to keep rows comparable. Effective bonuses against armor or cavalry ride on top in battle. Character heights for the same cast run on the companion heights page.

Forging raises each weapon differently, so rows pin the base.
