Quick answer

Binary result (1,024-based): 1,024 KiB = 1 MiB.“KB” here means KiB. Apps may label MiB “MB”.

Decimal result (1,000-based): 1,024 kB = 1.024 MB.This result uses standard decimal units.

Formula and worked example

Binary result (1,024-based)

“KB” here means KiB. Apps may label MiB “MB”.

MiB = KiB ÷ 1,024

Example (Binary result (1,024-based)): 1,500 KiB = 1.46484375 MiB.

Decimal result (1,000-based)

This result uses standard decimal units.

MB = kB ÷ 1,000

Example (Decimal result (1,000-based)): 1,500 kB = 1.5 MB.

KB, kB and KiB

The SI symbol for a decimal kilobyte is kB = 1,000 B. This converter accepts the familiar input alias KB for kB. KiB = 1,024 B is the IEC binary unit.

The binary result (1,024-based) reads the familiar input label “KB” as KiB and displays the result as MiB. The decimal result (1,000-based) accepts KB as an input alias for standard kB and displays the result as MB.

Match the definition used by your source: dividing KiB by 1,024 gives MiB; dividing decimal kB by 1,000 gives MB. Some apps display KiB/MiB with the shorter labels KB/MB. Read the 1000 vs 1024 explanation.

Standards and sources

Standard decimal prefixes use powers of 1,000: kB, MB, GB and TB. IEC binary prefixes use powers of 1,024: KiB, MiB, GiB and TiB. Results and formulas use these standard symbols.

The input controls keep familiar KB, MB, GB and TB labels. In the binary result (1,024-based), an unmarked input such as “MB” is read as MiB; some apps display a GiB result as “GB”. That compatibility explanation applies to this result only. In the decimal result (1,000-based), KB is an interface alias for standard kB (1,000 bytes); the unit factors do not change.

“The SI prefixes refer strictly to powers of 10. They should not be used to indicate powers of 2.”
