About this conversion

BioWare's Mass Effect Codex lists Reaper Destroyers at 160m (0.16km), the Normandy SR-1 at 170m (0.17km), the Normandy SR-2 at 216m (0.216km), Sovereign-class capital Reapers at 2km and the Citadel at 44.7km open length, so the station outweighs a Reaper twenty-two times over.

Sizes come from the in-game Codex (Reapers, Citadel 44.7km) via masseffect.fandom and GameBanshee, plus Wikipedia (Normandy SR-1 170m, SR-2 216m). 1 Citadel = 22.35x a Reaper (44.7/2), 1 Reaper = 12.5x a Destroyer, making this converter a handy reference for fleet debates, model scaling and everyday curiosity.

Units supported: Kilometers, miles, and fleet sizes (Destroyer 0.16km, SR-1 0.17km, SR-2 0.216km, Reaper 2km, Citadel 44.7km).

Source note: Sizes from BioWare's Mass Effect Codex — Reaper capital ships 2km, Destroyers 160m, Citadel 44.7km; Normandy SR-1 170m, SR-2 216m.
