Temperature Converter

This tool provides precise temperature conversions between Celsius, Fahrenheit, and Kelvin. It is designed for professionals and students who need fast, reliable conversions for experiments, design calculations, cooking recipes, HVAC specifications, or academic exercises. Users supply a numeric value and select the source and destination scales; the engine computes the result without rounding surprises and returns a single numeric value in the requested unit.
Core logic uses established thermodynamics relationships. Conversions follow direct formulas: F = C × 9/5 + 32; C = (F − 32) × 5/9; K = C + 273.15, with cross-pair conversions achieved by converting first to Celsius or Kelvin and then to the target unit. The calculation uses double‑precision arithmetic for consistency across ranges.
Benefits include consistent results, support for multiple units in a single session, and easy integration by developers in scripts or reports. It handles edge cases such as identical source and target units, negative kelvin inputs as errors, and extremely large values by providing clear failure signals and normalized outputs.
Localization and standards: uses SI units primarily; Fahrenheit support mirrors common US usage; Kelvin is included for scientific work. Decimal separators can follow locale settings; outputs are plain numbers with optional formatting. Exclusions: Rankine and other scales are not supported; batch conversions are not provided.
