Unit family

Data rate

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. Data rate describes bandwidth, transmission speed and storage throughput.

Data rate
Unit	Symbol	Formula
Bit per second	bit/s	base
Kilobit per second	kbit/s	1 kbit/s = 1000 bit/s
Megabit per second	Mbit/s	1 Mbit/s = 1000000 bit/s
Gigabit per second	Gbit/s	1 Gbit/s = 1000000000 bit/s
Terabit per second	Tbit/s	1 Tbit/s = 1000000000000 bit/s
Byte per second	B/s	1 B/s = 8 bit/s
Kilobyte per second	kB/s	1 kB/s = 8000 bit/s
Megabyte per second	MB/s	1 MB/s = 8000000 bit/s
Gigabyte per second	GB/s	1 GB/s = 8000000000 bit/s
Kibibyte per second	KiB/s	1 KiB/s = 8192 bit/s
Mebibyte per second	MiB/s	1 MiB/s = 8388608 bit/s
Gibibyte per second	GiB/s	1 GiB/s = 8589934592 bit/s

Factor origin

Factors come from the stored source family and are not derived from rounded display values.

Rounding rule

UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.

When not to use

Do not use as the sole basis for official, medical, safety-critical or contractual decisions.
