Convert kilobytes to megabytes, kibibytes to mebibytes, and compare KB, MB, bytes, GB, KiB, MiB, and related file size units for documents, images, downloads, uploads, apps, and digital storage.
KB to MB:
MB = KB ÷ 1,000
MB to KB:
KB = MB × 1,000
KiB to MiB:
MiB = KiB ÷ 1,024
MB to bytes:
bytes = MB × 1,000,000
KB to MB conversions are useful for documents, image files, email attachments, website assets, small downloads, uploads, storage limits, app data, PDFs, spreadsheets, compressed files, and cloud file storage.
Use this converter when comparing small file sizes, upload limits, storage requirements, and binary versus decimal file size units.
Your result shows the entered file size converted from the starting unit into the selected ending unit. The converter also shows reference values in bytes, KB, MB, GB, KiB, MiB, and GiB.
Decimal units such as KB and MB are based on 1,000. Binary units such as KiB and MiB are based on 1,024. Both are useful, but they can produce slightly different file size numbers.
In decimal storage, 1 MB equals 1,000 KB. In binary storage, 1 MiB equals 1,024 KiB.
Divide KB by 1,000 for decimal megabytes. For example, 2,500 KB equals 2.5 MB.
Divide KiB by 1,024. For example, 1,024 KiB equals 1 MiB.
No. KB usually means 1,000 bytes, while KiB means 1,024 bytes.
Some systems use decimal units and others use binary units. Formatting, compression, metadata, and storage overhead can also affect displayed file size.
