MB to KB Converter

This tool converts data sizes from megabytes to kilobytes for technical teams and students. It accepts a numeric MB value and returns the equivalent KB value. For example, 5 MB is 5120 KB under a 1024-based basis. The tool supports quick ad hoc checks, scripting workflows, and capacity planning where unit consistency matters.
Conceptually, MB and KB are size units with a defined ratio. The default factor is 1024 (1 MB = 1024 KB). An advanced option allows using a decimal basis of 1000 (1 MB = 1000 KB) to match decimal storage. The tool documents the basis used with each result to avoid ambiguity.
Core value lies in speed, precision, and predictable formatting. It serves software developers, system administrators, data engineers, and educators who need reliable conversions in code, reports, or dashboards. Core features include input validation, default factor by default, optional decimal basis, explicit basis documentation, and four-decimal output formatting.
