MB to GB Converter

Purpose & user intent: The MB to GB Converter solves the need for exact storage size conversions between megabytes and gigabytes. It targets developers, IT admins, data engineers, and storage planners who require quick, defensible size translations for capacity planning, documentation, logs, and data transfer estimates. The tool avoids manual arithmetic and provides immediate results with clear numeric output. It addresses ambiguity around decimal vs binary interpretations by offering an optional mode selection.

Core logic & features: The tool performs simple linear scaling between MB and GB. Required features include instant results, support for both conversion directions (MB→GB and GB→MB), and explicit numeric outputs. Optional/advanced features include a mode switch between Decimal (1 GB = 1000 MB) and Binary-like (1 GB ≈ 1024 MB) interpretations, plus adjustable output precision (1–6 decimals). It is designed for repeated, rapid conversions within technical workflows.

Inputs & outputs: Inputs consist of a numeric value, a source unit (MB or GB), a target unit, and an optional mode flag. Outputs provide a numeric value and the target unit, formatted per the selected mode and locale. Precision is controlled to suit reporting or automation.

Algorithms & calculations: In Decimal mode, MB→GB uses value / 1000 and GB→MB uses value × 1000. In Binary-like mode, MB→GB uses value / 1024 and GB→MB uses value × 1024. Rounding follows the user’s specified decimal places. The tool does not automatically convert to other units beyond MB/GB unless extended.

Error & edge cases: Non-numeric inputs are invalid; negative values are rejected; extremely large values may require scientific notation handling in downstream systems; if mode is omitted, Decimal mode is assumed by default. The tool assumes proper unit usage (MB or GB) and does not infer mixed units.

Industry/region & localization: Aligns with SI-based decimal conventions and common binary-like usage in IT contexts. Number formatting should respect locale conventions for decimal separators and thousands separators when integrated into broader systems.
Assumptions & exclusions: Assumes MB and GB as primary units; does not convert MiB/GiB explicitly; not a full storage inventory tool or a multi-unit converter beyond MB/GB in this iteration.
