In 1 bits there are 1.25000e-7 megabytes. Meanwhile in 1 megabytes there are 8,000,000 bits. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Megabytes to Bits calculator above to convert any number.

To convert bits to megabytes (MB), divide the number of bits by the right value for the megabyte standard you’re using.
Decimal (SI) megabyte conversion (common for storage and marketing):
1 MB = 1,000,000 bytes = 8,000,000 bits
Formula: MB = bits ÷ 8,000,000
Binary (MiB) conversion (common in some computer contexts):
1 MiB = 1,048,576 bytes = 8,388,608 bits
Formula: MiB = bits ÷ 8,388,608
Quick examples
16,000,000 bits ÷ 8,000,000 = 2 MB 16,000,000 bits ÷ 8,388,608 ≈ 1.907 MiBUse MB (decimal) unless you need MiB (binary) for a system that reports memory in powers of 2.
It depends on how you define megabyte. In data storage, 1 megabyte (MB) usually means 1,000,000 bytes, and each byte is 8 bits. That makes 1 MB equal to 8,000,000 bits.
In some cases, people mean mebibyte (MiB), which is 1,048,576 bytes. That equals 8,388,608 bits.
MB means megabytes, with a capital B for bytes. Mb means megabits, with a lowercase b for bits.
This matters because 1 byte equals 8 bits. So 1 MB equals 8 Mb.
Use this formula:
So if you have 80,000,000 bits:
Use this formula when you want the base-2 standard:
This is common in system memory and some technical tools.
1,000,000 is the base-10 definition used for many storage labels. 1,048,576 is the base-2 definition (2²⁰) used in binary-based systems.
Both are correct; they just measure megabytes in different ways.
A single bit is a very small amount of data.
First convert bits to bytes, then bytes to MB:
In the common base-10 definition:
If someone means 1 MiB instead:
Internet speeds almost always use bits, like Mbps (megabits per second). File sizes are usually shown in bytes, like MB.
That’s why a download speed of 80 Mbps doesn’t mean 80 MB per second. It’s closer to 10 MB per second (before overhead and slowdowns).
To convert a speed from bits per second to megabytes per second (MB/s):
Example:
Speed is often shown in Mb/s, while file size is shown in MB. You also lose some bandwidth to network overhead, server limits, and Wi-Fi issues.
A quick mental check helps:
The Calculate Box tool to convert bits to megabytes uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a bits value in the box and have it instantly converted to megabytes.
