About these units
megabyte (MB)
A megabyte (MB) is 1,000,000 bytes. Some operating systems show mebibytes (1,048,576 bytes) labeled MB, so the same file can appear with slightly different sizes.
Kilobytes to Megabytes
1 kB = 0.001 MB · 1 MB = 1,000 kB

How to convert kilobytes to megabytes
- Start from the exact relation:
1 kB = 0.001 MB - Put your value into the formula:
MB = kB ÷ 1,000 - Round to the precision you need. The tables on this page show 2 to 3 decimals.
Worked examples
130 ÷ 1,000 = 0.13 MB500 ÷ 1,000 = 0.5 MB
Mental-math shortcut
kB ÷ 1,000 is exact, not an estimate. Example: 130 kB = 0.13 MB.
Definition and source: SI prefixes are decimal: 1 kB = 1,000 B, 1 MB = 1,000 kB and 1 GB = 1,000 MB. The binary units (IEC 80000-13) are KiB = 1,024 B, MiB = 1,024 KiB and GiB = 1,024 MiB. Source: BIPM, The International System of Units (SI Brochure, 9th ed., 2019) (checked 2026-10-12).
