Going from Megabytes to Bytes means applying a fixed conversion factor: one Megabytes (MB) is exactly 1,048,576 Bytes (B). Type any number into the converter above and the equivalent updates instantly, or use the reference table for quick lookups.
Digital storage conversions matter for managing files, planning backups, comparing devices, and understanding internet speeds. The field has a famous complication: the difference between decimal and binary interpretations of the same unit names.
Understanding Megabytes and Bytes
Storage manufacturers typically use decimal units (1 GB = 1,000 MB), while operating systems often report in binary (1 GiB = 1,024 MiB). This is why a '1 TB' drive shows up as roughly 931 GB in your file manager. Bytes, kilobytes, megabytes, gigabytes, and terabytes form the everyday ladder of digital storage.
How accurate is this conversion?
The conversions here use the decimal (SI) standard where each step is a factor of 1,000, which matches how storage and bandwidth are marketed and sold. If your operating system reports different figures, it is using binary (1,024-based) units.
All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
Quick reference: common Megabytes to Bytes values
The most frequently searched conversions are 1 Megabytes = 1,048,576 Bytes, 5 Megabytes = 5,242,880 Bytes, 10 Megabytes = 10,485,760 Bytes, and 100 Megabytes = 104,857,600 Bytes. The full table further down covers every common value, and the calculator handles any number you need in between.
Pro tip: When buying storage, remember that advertised capacity is always decimal. A 500 GB drive holds 500 billion bytes, which your computer will display as about 465 GiB — that's not missing space, just a different counting system.
