warp Speed Chart

In the year 2063 humanity broke the warp barrior 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 by the Star Trek Encyclopedia.
