# All In One Calculator - Complete Unit Conversion Reference for LLMs

> Website: https://www.allinonecalculator.com
> Description: Comprehensive web application offering 78 unit converter categories and 1,600+ measurement units with client-side mathematical processing.

## System Architecture & Conversion Math

All In One Calculator processes conversions using base-unit ratio factors or dedicated conversion functions (for non-linear temperature scales and positional number systems).

### Linear Unit Formula
For linear measurement units:
Base Value = Input Value * Unit Factor
Output Value = Base Value / Target Unit Factor

### Temperature Formulas
- Celsius to Kelvin: K = C + 273.15
- Fahrenheit to Kelvin: K = (F + 459.67) * (5 / 9)
- Rankine to Kelvin: K = R * (5 / 9)
- Reaumur to Kelvin: K = r * 1.25 + 273.15

### Positional Base Conversions
Supports integer and fractional conversions between arbitrary bases (Base 2 through Base 36) using positional power expansion and radix division.
