General engineering utilities
Tech tools cover unit conversions, datetime math, color and number formatting, binary operations, QR code generation, Morse code, and random ID batching. They complement stack-specific Development and DevOps utilities when you need a quick calculator or encoder outside a particular framework.
Math and throughput estimators support capacity conversations; unit converters handle data-size and rate translations during design docs. Markdown preview and URL builders help draft content and links without leaving the browser.
When to reach for these tools
Use this category for ad hoc calculations, prototyping identifiers, or preparing human-readable output for documentation. Verify precision-sensitive results against domain requirements, especially for financial or scientific units.
Each page explains the underlying concepts and lists related tools so you can chain workflows without returning to the home catalog.
