This converter turns megabytes into bytes instantly, using the exact factor 1 megabyte = 1000000 bytes. 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. Eight bits; the addressable unit of computer memory.
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
1000000- The exact number of bytes in one megabyte
bytes- The converted result
How it works, step by step
- Enter the number of megabytes you want to convert.
- The value is multiplied by 1000000, the exact conversion factor.
- The result is displayed in bytes, 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 1000000. That gives 5,000,000 bytes. A quick sanity check: one megabyte is larger than one byte, so the number should get bigger — and it does.
Converting 72 megabytes
72 × 1000000 = 72,000,000 bytes. Working backwards, 72,000,000 ÷ 1000000 returns 72 megabytes, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many bytes are in one megabyte?
Exactly 1000000. 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 bytes?
Bytes = megabytes × 1000000. To reverse it, divide instead: megabytes = bytes ÷ 1000000, which is the same as multiplying by 1e-06.
Is the megabyte bigger than the byte?
Yes. One megabyte equals 1e+06 bytes, so it is the larger unit.
Why does my answer differ slightly from other megabytes to bytes 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.
