Time Converter

Purpose & User Intent: This tool provides rapid conversion between common time units including ms, s, min, hr, d, wk. It accepts a numeric input, a source unit, and a target unit, and returns the converted value. Target users include developers, data analysts, educators, and planners who need quick, reliable duration conversions in code, reports, or schedules.
Core Logic & Features: Required inputs are value, from_unit, to_unit. Outputs include converted_value. Optional features include precision control, batch conversion, and future unit expansions. Units are mapped to a fixed base of seconds; conversions use a fixed factor table. Validation ensures numeric value and supported units; negative values are allowed.
Algorithms & Calculations: The core formula is output = value × (from_factor ÷ to_factor) after mapping every unit to seconds (e.g., 1 min = 60 s, 1 hr = 3600 s, 1 wk = 604800 s). The method supports integer and decimal inputs and enforces consistency across environments.
Error & Edge Cases: Invalid units or non-numeric input produce explicit errors. Very large or very small values are handled with standard floating-point precision; NaN or Infinity are rejected.
Industry & Localization: Uses standard time units and English abbreviations; decimals use a dot; no locale specific formatting implied.
Assumptions & Exclusions: Not a calendar duration tool; does not account for varying month lengths or time zones; does not compute durations across daylight saving transitions.
