1 MB = 976.5625 KiB IEC ↔ SI conversion

The Megabytes (MB) to Kibibytes (KiB) Converter turns your Megabyte (MB) value into Kibibytes (KiB). Type your storage value in the input field — 1 MB = 976.5625 KiB, calculated across both decimal (SI) and binary (IEC) standards.

Megabytes (MB) to Kibibytes (KiB) Converter

How to Convert Megabytes to Kibibytes

To convert megabytes (decimal/SI) to kibibytes (binary/IEC), multiply by 976.5625. Decimal units use base 1,000, while binary units use base 1,024. See also: Kibibytes to MB.

MB is a decimal (SI) unit—what storage manufacturers advertise. 1 MB = 1,000 of the smaller unit. Use our convert MB to Terabits.

KiB is a binary (IEC) unit—what operating systems often display. 1 KiB = 1,024 of the smaller unit. See also: Kilobytes to KiB calculator.

1 MB = 976.5625 KiB (using SI decimal standard) — which means there are 976.5625kibibytes in every megabyte.

MB to KiB Conversion Formula

// Convert MB to KiB
KiB = MB × 976.5625

// Reverse: Convert KiB to MB
MB = KiB × 0.001024

SI Decimal vs Binary: Why Two Different Standards?

When converting megabytes to kibibytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:

SI decimal vs binary storage standards: base, kilobyte size and common users
Standard	Base	1 KB equals	Used By
SI Decimal	1000	1,000 bytes	Hard drive manufacturers, macOS, network speeds
Binary (IEC)	1024	1,024 bytes	Windows, Linux (partially), RAM specifications

Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
