Enter a value to see conversions
What is this tool?
Unit Converter is a specialized tool designed for software developers and IT professionals to quickly convert between units commonly used in programming, system administration, and web development. Unlike generic converters, this tool focuses on digital units like data sizes, transfer rates, time durations, CPU frequencies, and CSS measurements.
Key Features
- SI vs IEC Modes: Toggle between decimal (1 MB = 1,000 KB) and binary (1 MiB = 1,024 KiB) standards for accurate calculations
- Real-time Conversion: Instantly see conversions to all supported units as you type
- Formula Display: Learn the math behind each conversion with visible formulas
- Developer Helpers: Calculate Base64 overhead, UTF-8 byte lengths, and download ETAs
- CSS Units: Convert responsive design units with configurable viewport and font sizes
Common Use Cases
Performance Optimization
Convert memory usage metrics from profiling tools (bytes → MB/GiB) to understand application resource consumption and identify optimization opportunities.
Network Analysis
Convert bandwidth measurements (Mbps → MB/s) to calculate actual download speeds and estimate transfer times for API payloads or file uploads.
API Documentation
Format data size limits in human-readable units (e.g., "Max payload: 5 MB" instead of "5242880 bytes") for clear API documentation.
Responsive Web Design
Convert CSS units (px → rem → vw) to create fluid, accessible designs that scale properly across devices and respect user font size preferences.
Base64 Planning
Estimate encoded payload sizes before implementing Base64 encoding for embedded resources or API data transmission.
Time Tracking
Convert millisecond timestamps from logs or metrics into human-readable durations for debugging and performance analysis.
Understanding SI vs IEC
SI (Decimal): Uses powers of 1000. This is the standard for storage manufacturers and modern operating systems. Example: 1 MB = 1,000,000 bytes.
IEC (Binary): Uses powers of 1024. Common in system memory and older systems. Example: 1 MiB = 1,048,576 bytes.
💡 Tip: When a hard drive says "1 TB" but shows "931 GB" in your OS, that's because manufacturers use SI (1 TB = 1,000 GB) while systems use IEC (931 GiB).
