The megabyte
The megabyte (MB) equals 1,000,000 bytes (decimal) or 1,048,576 bytes (binary, formally 'mebibyte' MiB — a roughly 5% difference). Used for music files, photographs, and most everyday document sizes.
250 Megabytes to Kilobytes
250 MB = 250000 kB (megabyte → kilobyte)
250 MB = 250000 kB
250 megabytes (MB) equals 250000 kilobytes (kB). The conversion uses the exact factor 1000: 250 × 1000 = 250000.
Formula
Kilobytes = Megabytes × 1000Quick

When to use megabytes → kilobytes
Megabytes to kilobytes multiplies by 1000. Useful when a coarse MB-level budget (say, a 5 MB upload limit on a web form) needs to be checked against a collection of kB-sized files — 5 MB is 5000 kB, so roughly 500–1000 typical email-sized attachments, or a handful of higher-resolution images, depending on compression.
Game asset pipelines use this when packing a texture budget: a 3 MB budget per character texture set is 3000 kB, which a compression pass then has to fit multiple mipmap levels into — artists working in kB-denominated tools (many texture compressors report kB by default) need this conversion to check their output against an MB-stated engine budget before a build ships over its memory ceiling.

Real-world reference
A typical 3-minute MP3 is around 3–7 MB. A high-resolution JPEG photo is 2–8 MB. In kilobytes, that gives you: 1 MB = 1000 kB, 10 MB = 10000 kB, 100 MB = 100000 kB.

About the megabyte and the kilobyte
The kilobyte
The kilobyte (kB) equals exactly 1,000 bytes in the SI/IEC decimal convention. Most modern OS file managers and storage-vendor marketing use this definition. Older operating systems (Windows up to Vista) used 1 kB = 1,024 B — that value is now strictly called the kibibyte (KiB).
