What does STS1 (signal) represent?

STS1 (signal) is the basic SONET electrical frame unit carrying a line rate of 51.84 megabits per second, including overhead and framed every 125 microseconds.

Why convert STS1 to gigabit/second (SI def.)?

Converting STS1 to gigabit/second (SI def.) expresses SONET line rates in a standardized unit commonly used for networking link capacities and throughput.

Is a gigabit per second the same as a gibibit per second?

No, a gigabit per second (SI) equals 10^9 bits per second, while a gibibit per second uses a binary factor of 2^30, so they are different units.
