Examples

011 Gbit/s = 0.125 GB/s

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Mbit/s and MB/s differ by a factor of eight because one byte holds eight bits. Providers usually advertise Mbit/s while download tools display MB/s.

03Base unit: bit/s

1 Gbit/s = 1000000000 bit/s. Then the value is converted through the base unit bit/s into Gigabyte per second.
