The megalight per hour (abbreviated MGLT) was a unit used to measure the relative speed of starships in realspace (as opposed to hyperspace), although the velocities were still far greater than the speed of light, just like the velocities of starships in hyperspace.[1] One megalight per hour was approximately 0.0755 light-years per hour,[2][1] 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]
The starship with the fastest known maximum realspace speed, the TIE/vn space superiority fighter, had a maximum realspace speed of 155 MGLT[4], or approximately 102,513.9 times the speed of light.[1]

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]

Notes and references[]
- ↑ 1.0 1.1 1.2 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.
