Megabit per second to Kilobit per second

Exact answer: 1 Mbit/s = 1000 kbit/s (exact – SI decimal prefix)

Megabit per second and Kilobit per second both belong to the Data rate family. The difference is a decimal prefix, so the factor is a clean power of ten. Data rate describes bandwidth, transmission speed and storage throughput.

Examples

010.5 Mbit/s = 500 kbit/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 Mbit/s = 1000000 bit/s. Then the value is converted through the base unit bit/s into Kilobit per second.
