Megabytes to Mebibytes Converter
Convert decimal megabytes to binary mebibytes and back.
Compare decimal and binary megabyte scales
Megabytes use powers of one thousand, while mebibytes use powers of 1,024. Software and hardware labels do not always use the terms consistently, which can make identical byte counts appear different. This page converts the formal definitions in either direction.
The default 1 MB converts to 0.953674 MiB. In reverse, 1 MiB converts to 1.04858 MB. The reference table helps compare common file and memory quantities while retaining six significant figures for values that do not convert to a short decimal.
Private capacity conversion only
No file or device is examined, and the entered capacity stays in your browser. Compression, filesystem allocation, transfer encoding, and application overhead can change real storage usage. This calculator addresses only the defined relationship between MB and MiB.
Frequently Asked Questions
How many bytes are in a megabyte?
A decimal megabyte is 1,000,000 bytes.
How many bytes are in a mebibyte?
A mebibyte is 1,048,576 bytes, or two to the twentieth bytes.
Are MB and MiB interchangeable?
No. They are close but distinct, and the difference matters when comparing file sizes, memory, and transfer limits.
