What is the difference between terabit/second and terabyte/second?

Terabit/second measures data transfer in bits per second, whereas terabyte/second measures data in bytes per second, with 1 byte equal to 8 bits.

Why is the conversion factor approximately 0.1374?

Because 1 terabit equals 10^12 bits and 1 terabyte (SI) equals 10^12 bytes, and since 1 byte equals 8 bits, converting bits to bytes divides the value by 8.

In what scenarios would I convert terabit/second to terabyte/second?

This conversion is helpful when relating network data transfer speeds (in bits) to storage or system throughput speeds (in bytes) in data centers or HPC environments.
