Dev Unit Converter handles developer-specific unit categories that generic converters miss: data with IEC/SI base toggle, CSS units with configurable viewport and font-size, LLM tokens with model-specific tokenizer ratios for GPT-4, Claude, Llama-3, and Gemini, plus time and frequency. Every conversion returns the numeric result, a formatted string, and the formula.

How to use

1. Select category — data, tokens, css, time, or frequency.
2. Enter value and units — Provide the numeric value and source/target units.
3. Configure options — For data: choose IEC (1024) or SI (1000). For tokens: pick the LLM model. For CSS: set base font size and viewport.
4. Convert — Click Convert or press Ctrl+Enter. The result shows the formatted value and the exact formula used.
