This page converts bytes per second into megabytes per second using the factor 1e-06, 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.
One byte per second is eight bits per second. File transfer tools report bytes, which is the single most common source of confusion about whether a connection is running at its rated speed. 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.
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. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in megabytes per second, so you can sanity-check whether your answer is a plausible size.
The formula
bytes per second- The amount you are converting, in bytes per second
1e-06- The exact number of megabytes per second in one byte per second
megabytes per second- The converted result
How it works, step by step
- Enter the value in bytes per second.
- It is multiplied by 1e-06, 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: 1e+06 B/s in megabytes per second
Take hd video stream, roughly 1e+06 B/s. The conversion is a single multiplication — 1e+06 × 1e-06 — giving 1 MB/s. Because the relationship is proportional, doubling the input doubles the answer to 2 MB/s.
4K video stream: 3.12e+06 B/s in megabytes per second
Take 4k video stream, roughly 3.12e+06 B/s. The conversion is a single multiplication — 3.12e+06 × 1e-06 — giving 3.12 MB/s. Because the relationship is proportional, doubling the input doubles the answer to 6.24 MB/s.
How to read your score
Frequently asked questions
How many megabytes per second are in one byte per second?
Exactly 1e-06. 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 bytes per second to megabytes per second?
megabytes per second = bytes per second × 1e-06. Reversed, bytes per second = megabytes per second ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the byte per second or the megabyte per second?
The megabyte per second. One byte per second is only 1e-06 of a megabyte per second, so it takes 1e+06 bytes 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 byte per second?
One byte per second is eight bits per second. File transfer tools report bytes, which is the single most common source of confusion about whether a connection is running at its rated speed.
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.
