vfl converter

About This Tool

Purpose: The vfl converter provides instant, cross-domain unit conversions across length, area, volume, mass, temperature, velocity, energy, and derived units. It targets engineers, scientists, students, technicians, and analysts who need quick, repeatable conversions during design, analysis, data preparation, or fieldwork. Example: 10 m → 32.8084 ft; 5 L → 1.32086 gal; 100 C → 212 F.
Core Logic: Supports SI and imperial units, including derived units such as m^2, m^3, L/s, J/kg. Required: numeric input, source and target units, and a precise result. Optional: batch conversions, history, locale-aware formatting, and user-defined unit aliases.
Inputs & Outputs: Inputs: value (number), from_unit (string), to_unit (string), optional precision (integer), locale. Outputs: converted_value (number) and the target unit; formatting rules describe decimal places and locale rules.
Algorithms & Calculations: Conversion uses a base-unit mapping; each unit has a factor to a canonical base; temperatures use offset formulas (C, F, K). Example: meters to feet uses factor 3.28084; Celsius to Fahrenheit uses (C × 9/5) + 32.
Error & Edge Cases: Incompatible unit pairs raise a domain error; non-numeric values or missing inputs trigger validation failures; extreme values trigger overflow/underflow checks. Industry/Region & Localization: Default base is SI with optional imperial equivalents; supports locale-specific decimal separators, thousands separators, and unit naming conventions; temperature scales include C/F/K. Assumptions & Exclusions: Currency, time-based rates, and pricing are outside scope; the tool assumes standard unit symbols and does not address instrument calibration or uncertainty propagation. Interoperability: The converter can be integrated via API, returning a stable numeric value and unit and providing structured error information for downstream tools.
