How to convert megabits to megabytes
To convert megabits (Mb) to megabytes (MB), multiply the value in megabits by 0.125.
MB = Mb × 0.125 (decimal)
MB = Mb × 0.119209289551 (binary)
Example: 5 Mb = 0.625 MB, or 0.5960464478 MB in binary.
Decimal (SI) counting steps by 1,000 and is what drive makers, macOS and phones use. Binary counting steps by 1,024 and is what Windows and RAM use; its unambiguous IEC names are KiB, MiB and GiB. Bits are decimal either way.
You can also type 5 Mb to MB into the smart calculator, or mix units: 1 Mb + 1 MB.

About the units
Megabit (Mb)
One million bits. Internet speeds are sold in megabits per second.
Megabyte (MB)
In decimal mode 1,000,000 bytes (1,000 KB); in binary mode 1,048,576 bytes (1,024 KB).
Digital storage is counted in bits and bytes (1 byte = 8 bits). There are two ways to count bytes. Decimal (SI) prefixes step by 1,000: 1 KB = 1,000 B and 1 GB = 1,000 MB, which is how drive makers, macOS, iOS and Android report sizes. Binary prefixes step by 1,024: 1 KB = 1,024 B and 1 GB = 1,024 MB, which is how Windows and RAM count (the IEC names for these are KiB, MiB and GiB). Bits are always decimal: 1 Kb = 1,000 b.
Questions and answers
How many megabytes are in a megabit?
One megabit (Mb) equals 0.125 megabytes in decimal (SI) counting, or 0.1192092896 megabytes in binary counting (1 KB = 1,024 B), which Windows uses.
How do I convert megabits to megabytes?
To convert megabits to megabytes, multiply the value in megabits by 0.125. The formula is MB = Mb × 0.125. For example, 5 Mb = 0.625 MB.
What is 5 Mb in MB?
5 megabits is 0.625 megabytes.
Which is bigger, a megabit or a megabyte?
A megabyte is bigger: 1 MB = 8 Mb.
Is 1 GB equal to 1,000 MB or 1,024 MB?
Both are in use. In decimal (SI) counting, which drive makers, macOS, iOS and Android use, 1 GB = 1,000 MB. In binary counting, which Windows and RAM use, 1 GB = 1,024 MB; the unambiguous IEC name for that size is the gibibyte (GiB). ConvertEasy has a Decimal / Binary switch so KB, MB, GB and TB follow whichever you need, while KiB, MiB and GiB are always binary.
Are kilobits 1,000 or 1,024 bits?
ConvertEasy treats bits as decimal in both modes: 1 Kb = 1,000 b, 1 Mb = 1,000 Kb. A byte is always 8 bits, so only byte units (KB, MB, GB…) change with the switch.
Does this Mb to MB converter work offline?
Yes. ConvertEasy is a progressive web app: after your first visit it keeps working with no connection, and you can install it to your home screen from the browser menu.
