To convert bits per second to megabits per second, multiply by 1e-06. That factor is the whole relationship: both units measure how much data moves per second, so the conversion is a proportion with no offset and no substance-specific constant.
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. Megabits per second is how every broadband package is advertised. The figure is bits, so divide by eight to get the download speed your browser will show.
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 megabits 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
1e-06- The exact number of megabits per second in one bit per second
megabits per second- The converted result
How it works, step by step
- Enter the value in bits per second.
- It is multiplied by 1e-06, the exact factor between the two units.
- The answer is shown in megabits per second, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
SD video stream: 3e+06 bit/s in megabits per second
Take sd video stream, roughly 3e+06 bit/s. The conversion is a single multiplication — 3e+06 × 1e-06 — giving 3 Mbit/s. Because the relationship is proportional, doubling the input doubles the answer to 6 Mbit/s.
HD video stream: 8e+06 bit/s in megabits per second
At 8e+06 bit/s (hd video stream), the same quantity in megabits per second is 8e+06 × 1e-06 = 8 Mbit/s. One bit per second is 1e-06 megabits per second, so the numbers shrink as expected.
How to read your score
Frequently asked questions
How many megabits per second are in one bit 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 bits per second to megabits per second?
megabits per second = bits per second × 1e-06. Reversed, bits per second = megabits per second ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the bit per second or the megabit per second?
The megabit per second. One bit per second is only 1e-06 of a megabit per second, so it takes 1e+06 bits per second to make one megabit 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 megabit per second?
Megabits per second is how every broadband package is advertised. The figure is bits, so divide by eight to get the download speed your browser will show.
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.
