How fast is warp speed?

7 Comments

In the year 2063 humanity broke the warp barrier when Zefram Cochrane launched the “Phoenix” and flew at the speed of light. Since that time Earth, and later the Federation, continued to develop faster warp engines. By the late 24th Century, a few starships were able to travel at speeds matching 9.999, allowing Starfleet to explore even further into the unknown.

This section gives a general guideline on warp speed conversion as offered in the Star Trek Starfleet Technical Manual.

  1. Nice chart. More readily understandable for those without a thorough education in physics or mathematics. I also like the reference to the Star Fleet technical manual. However, I would probably choose to represent, as is “normally” the case) velocity in miles per second. (mos), instead of (or at least along with) miles per hour (mph). But the mph is fun to see.

    1. Thanks for the praise, Jeff!

      I settled on using mph so it’s easier for the common folk to compare speeds with the Ludicrous Mode of their Tesla’s 😀

    1. i believe that the scale changes from tos to tng, where in tos there is no specified limit, and in tng warp ten is infinite velocity. warp ten in tos is roughly equivalent to warp 8 tng

  2. I’m trying to figure out what is 80.213 x that of light is in warp speed 4.5 or a shade under warp 4.7 guessing I need help figuring it out. Thanks.
