This page converts bits per second into megabytes per second using the factor 1.25e-07, and shows the reverse figure alongside it. Both units measure how much data moves per second, which is why one number does the whole job.
Megabytes per second is the honest measure of transfer speed, and the unit disk benchmarks use. An 8 MB/s transfer is a 64 Mbps link running flat out. One bit per second is the base unit of data rate. Network speeds are always quoted in bits, which is why a 100 Mbps line downloads at about 12 MB/s.
Bits and bytes. Network speeds are sold in bits per second and file transfers are reported in bytes per second, and there are eight bits to a byte, so a 100 Mbps line downloads at about 12 MB/s. A connection is not underperforming by a factor of eight; it is being measured in different units. Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into megabytes per second, which is usually more useful than the bare number.
The formula
bits per second- The amount you are converting, in bits per second
1.25e-07- The exact number of megabytes per second in one bit per second
megabytes per second- The converted result
How it works, step by step
- Enter the value in bits per second.
- It is multiplied by 1.25e-07, the exact factor between the two units.
- The answer is shown in megabytes per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
HD video stream: 8e+06 bit/s in megabytes per second
Take hd video stream, roughly 8e+06 bit/s. The conversion is a single multiplication — 8e+06 × 1.25e-07 — giving 1 MB/s. Because the relationship is proportional, doubling the input doubles the answer to 2 MB/s.
SD video stream: 3e+06 bit/s in megabytes per second
Take sd video stream, roughly 3e+06 bit/s. The conversion is a single multiplication — 3e+06 × 1.25e-07 — giving 0.375 MB/s. Because the relationship is proportional, doubling the input doubles the answer to 0.75 MB/s.

Frequently asked questions
How many megabytes per second are in one bit per second?
Exactly 1.25e-07. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert bits per second to megabytes per second?
megabytes per second = bits per second × 1.25e-07. Reversed, bits per second = megabytes per second ÷ 1.25e-07, which is the same as multiplying by 8,000,000.
Which is the bigger unit, the bit per second or the megabyte per second?
The megabyte per second. One bit per second is only 1.25e-07 of a megabyte per second, so it takes 8e+06 bits per second to make one megabyte per second.
What does this quantity actually measure?
Both units measure how much data moves per second. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a bit per second?
One bit per second is the base unit of data rate. Network speeds are always quoted in bits, which is why a 100 Mbps line downloads at about 12 MB/s.
What is a megabyte per second?
Megabytes per second is the honest measure of transfer speed, and the unit disk benchmarks use. An 8 MB/s transfer is a 64 Mbps link running flat out.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
