FAQ
What is the conversion factor from MB to KiB?
1 MB equals 976.5625 KiB. To convert, multiply the value in megabytes by 976.5625.
How do I convert 1 MB to KiB?
1 MB = 976.563 KiB. For any value, multiply by 976.5625.
How do I convert KiB back to MB?
Divide by the same factor — or equivalently, multiply by 0.001024. So 1 KiB = 0.001024 MB.
When would I need to convert megabyte to kibibyte?
Digital data-storage conversions between MB and KiB are routine in IT, networking, storage-array engineering, datacenter capacity planning, cloud-cost reconciliation, embedded systems and scientific data acquisition. Decimal (SI) units (kB, MB, GB, TB, PB) use base-10 multiples: 1 kB = 1,000 bytes. Binary (IEC 80000-13) units (KiB, MiB, GiB, TiB, PiB) use base-2 multiples: 1 KiB = 1,024 bytes. 1 byte = 8 bits exactly across both ladders. This category is storage size only — it does NOT cover data-transfer rate (bit/s, MB/s), download-time, bandwidth, compression-ratio assumptions or storage-pricing calculators, all of which require additional information beyond a single linear factor.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
