Warp Factor

Warp factor was the primary means of measuring speeds attained using warp drive. An alternative term time-warp factor was also used. The term was often shortened to warp when followed by its value, so that saying "warp six" is the same as saying "warp factor six." Faster-than-light travel began after warp one, whereas lower fractional values were sometimes used to measure sublight speeds. Spacecraft ordinarily traveled at a higher integer warp factor.

By the 24th century, infinite velocity was designated as warp factor ten. It was considered to be unattainable by conventional means. Because of this, extremely high warp factors were indicated with decimal values between nine and ten, such as warp 9.975.
