This converter turns megabytes into megabits instantly, using the exact factor 1 megabyte = 8 megabits. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
One million bytes; the unit for photos and documents. One million bits — how internet speeds are advertised.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
megabytes- The amount you are converting, measured in megabytes
8- The exact number of megabits in one megabyte
megabits- The converted result
How it works, step by step
- Enter the number of megabytes you want to convert.
- The value is multiplied by 8, the exact conversion factor.
- The result is displayed in megabits, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 megabytes
Multiply 5 by 8. That gives 40 megabits. A quick sanity check: one megabyte is larger than one megabit, so the number should get bigger — and it does.
Converting 72 megabytes
72 × 8 = 576 megabits. Working backwards, 576 ÷ 8 returns 72 megabytes, which confirms the factor is applied the right way round.

Frequently asked questions
How many megabits are in one megabyte?
Exactly 8. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert megabytes to megabits?
Megabits = megabytes × 8. To reverse it, divide instead: megabytes = megabits ÷ 8, which is the same as multiplying by 0.125.
Is the megabyte bigger than the megabit?
Yes. One megabyte equals 8 megabits, so it is the larger unit.
Why does my answer differ slightly from other megabytes to megabits converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
What is a megabyte?
