1 Mbit/s =
| Bit per second | 1,000,000 bit/s |
| Kilobit per second | 1,000 kbit/s |
| Gigabit per second | 0.001 Gbit/s |
| Byte per second | 125,000 B/s |
| Kilobyte per second | 125 KB/s |
| Megabyte per second | 0.125 MB/s |

About this calculator
Data transfer rate measures how fast information moves across a network or bus. Network speeds are usually quoted in bits per second (Mbit/s, Gbit/s), while file managers and download tools typically report bytes per second (MB/s, GB/s). Since one byte is 8 bits, the two differ by a factor of 8.
This converter uses the bit per second as its base unit and decimal (SI) prefixes, so one kilobit is 1000 bits. That means a 100 Mbit/s connection delivers a maximum of about 12.5 MB/s. Use it to translate internet plan speeds into real-world download rates.
Frequently asked questions
Because there are 8 bits in a byte. 100 Mbit/s divided by 8 equals 12.5 MB/s — both numbers describe the same speed.
Divide the bit rate by 8. For example, 80 Mbit/s equals 10 MB/s.
This converter uses decimal SI prefixes, so 1 kbit/s = 1000 bit/s, matching how network speeds are advertised.
