File Size Converter

About This Tool

The tool computes data size conversions across common units for decimal and binary families. Typical users include developers, database administrators, system engineers, data analysts, and students who estimate storage capacity, file transfer plans, backups, or cloud quotas. It supports quick, precise computations without manual arithmetic and is suitable for both ad hoc checks and embedded workflows in data pipelines.
Conceptual operation is twofold: quantify the input size in a chosen source unit and normalize to a base scale, then re-express the value in the target unit. The tool uses 1000-based factors for decimal units (KB, MB, GB, TB) and 1024-based factors for binary units (KiB, MiB, GiB, TiB). Results are delivered with configurable precision and optional rounding.
Core value and use cases include capacity planning, storage cost estimation, and data transfer budgeting for networks, databases, and cloud environments. Advanced features allow explicit unit lists, mixed-unit conversions, integer-only results, and a small reference of aggressive ranges to flag potential overflows. It also handles very large values and reports exact and approximate results depending on the chosen mode.
Data integrity and extensibility: the system validates inputs, rejects invalid units, and provides deterministic outputs regardless of locale. It can be integrated into scripts and dashboards via a simple API surface, enabling automation tasks such as nightly migrations, size audits, and compliance reporting.
