The megalight per hour (abbreviated MGLT) was a unit used to measure the relative sublight speed of starships in realspace. One megalight per hour was approximately 0.0755 light-years per hour,[1] [2] or about 661.38 times the speed of light.

For example, the RZ-1 A-wing interceptor was markedly faster (120 MGLT) than the BTL-A4 Y-wing assault starfighter/bomber (70 MGLT).[3]

Behind the scenes[]

Industrial Light & Magic's spaceship speed and maneuverability chart created for Star Wars: Episode VI Return of the Jedi

The MGLT unit originated in a reference chart comparing the propulsive capabilities of starfighters, drawn by Industrial Light & Magic during the production of Star Wars: Episode VI Return of the Jedi.[6] Some of the figures provided in Star Wars Super Graphic: A Visual Guide to a Galaxy Far, Far Away are markedly different[3] than those shown on the original diagram.[6]

  2. According to Raymus, the Tantive IV can cover 0.25 parsecs (about 0.81 light-years) in 8 minutes at full sub-light speed (81 MGLT). This means it covers about 6.11 light-years per hour, so 81 MGLT ≈ 6.11 light-years per hour. We can thus conclude that 1 MGLT ≈ 0.0755 light-years per hour.
