Formula
Megabytes = Kilobytes ÷ 1,024
MB = KB × 0.0009765625
In binary convention, 1 MB = 210 KB = 1,024 KB, so dividing kilobytes by 1,024 converts to megabytes. The decimal equivalent is 1 ÷ 1,024 = 0.0009765625.
How it works
Kilobytes and megabytes are adjacent steps on the binary prefix ladder; each step is a factor of 1,024 (210). Moving up from KB to MB means dividing by 1,024, which is the same as multiplying by 0.0009765625.
A common mistake is dividing by 1,000 instead of 1,024. Many internet-speed and older-software contexts loosely treat 1 MB as 1,000 KB, but most operating systems and filesystems use 1,024, so using the wrong divisor introduces a roughly 2.4% error.
Worked example
Convert 1,024 KB to MB
- Start with 1,024 KB.
- Divide by 1,024 (one binary prefix step): 1,024 ÷ 1,024 = 1.
- Confirm: 1,024 × 0.0009765625 = 1.0 MB.
1,024 KB = 1.0 MB
Common mistakes to avoid
- Dividing by 1000 instead of 1024 in binary contexts -- a 1440 KB floppy disk image is 1.40625 MiB, not 1.44 MB, causing confusion when comparing to marketed capacity.
- Confusing kilobytes (KB) with kilobits (Kb) -- network packet sizes are sometimes listed in kilobits; 512 Kb = 64 KB, not 512 KB.
- Thinking kilobytes and kibibytes are always equivalent -- IEC defines 1 KiB = 1024 bytes, while SI defines 1 kB = 1000 bytes; many tools use them interchangeably but they differ.
Key terms
- Kilobyte (KB)
- A unit of digital storage equal to 1,024 bytes in binary convention.
- Megabyte (MB)
- A unit of digital storage equal to 1,024 kilobytes (220 bytes) in binary convention.
- Binary prefix
