About this converter
Star Trek publishes starship lengths the way navies publish hull numbers. The Enterprise-D runs 642 meters over 42 decks, Voyager 343, the Defiant a stocky 170. Klingon and Romulan hulls scale bigger per crew: the Vor'cha at 481, the D'deridex past a kilometer, the Borg Cube at 3,000 meters a side. Stations are diameters and shuttles are shuttles, each labeled. Every figure here is the standard tech manual or Encyclopedia value with the famous alternative noted, like the refit Constitution at 305. The Borg Cube at 3000 meters is more than twice Deep Space Nine at 1451, while the Delta Flyer at 21 meters is the smallest craft here.
How to use it
Pick two vessels and a unit in the top row. The three boxes below stay linked: one holds a count of the first, one the matching count of the second, one the length in the chosen unit. Change any box and the other two update. Try 1 Borg Cube against Defiants.
Kelvin-timeline ships like the Vengeance run larger and stay out of this prime-timeline table. Size classes, not battle outcomes: a Bird of Prey has killed bigger ships.
