Data transfer converter
Internet speeds are sold in megabits per second (Mbps); downloads show megabytes per second (MB/s). 8 bits make a byte.
1 megabit per second = 0.125 megabytes per second
How it’s calculated
MB/s = Mbit/s ÷ 8
- Divide the value in megabits per second by 8.
- Equivalently, multiply by 0.125.
- 1 Mbit/s = 0.125 MB/s · 1 MB/s = 8 Mbit/s

Find the conversion factor
By definition 1 Mbit/s = 1000000 bit/s and 1 MB/s = 8000000 bit/s, so 1 MB/s = 8 Mbit/s. Source: IEC 80000-13 (decimal and binary prefixes).
Multiply by the factor written as a fraction
Put Mbit/s in the denominator so it cancels, leaving MB/s.
Calculate (unrounded)
Round the answer
Rounded to 5 significant figures.
Answer: 0.125 MB/s
1 Mbit/s in other units
Batch convert Mbit/s → MB/s
- 1 Mbit/s = 0.125 MB/s
- 5 Mbit/s = 0.625 MB/s
- 10 Mbit/s = 1.25 MB/s
- 25 Mbit/s = 3.125 MB/s

Frequently asked questions
Which data transfer units can I convert?
bits per second (bit/s), kilobits per second (kbit/s), megabits per second (Mbit/s), gigabits per second (Gbit/s), bytes per second (B/s), kilobytes per second (kB/s), megabytes per second (MB/s), gigabytes per second (GB/s), mebibytes per second (MiB/s).
How accurate are the results?
Every unit is stored with its exact defining factor (NIST SP 811, NIST Handbook 44 or the BIPM SI Brochure). Calculations use double-precision arithmetic and are rounded only for display, to 5 significant figures by default (trailing zeros dropped, so 1 km shows as 1000 m). You can choose Auto (up to 10 digits), fixed decimals or more significant figures, or switch to scientific or engineering notation.
