About the units
- Mebibyte
- A binary unit equal to exactly 2^20 = 1,048,576 bytes, which is 1024 kibibytes.
- Megabyte
- A decimal unit equal to exactly 1,000,000 bytes (10^6), different from the binary mebibyte of 1,048,576 bytes.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many megabytes are in one mebibyte?
1 MiB = 1.04858 MB exactly.
How do I convert mebibytes to megabytes?
Use MB = MiB × 1.048576. For example, 25 MiB = 26.2144 MB.
How many mebibytes are in one megabyte?
1 MB = 0.953674 MiB.
Why does a 1 TB drive show about 931 GB on my computer?
Drive makers count 1 TB as 10^12 bytes, while Windows divides by 2^30 and labels the result GB even though it is really GiB. So 10^12 ÷ 1,073,741,824 gives about 931.32, and no space is missing.
What is the difference between a kilobyte and a kibibyte?
A kilobyte (kB) is a decimal unit of 1000 bytes and a kibibyte (KiB) is a binary unit of 1024 bytes. The same split applies to mega and mebi, giga and gibi, and the gap grows at each step.
