Unit Converter Feet and Inches to Meters

Purpose & user intent: This tool solves the problem of converting imperial height or length measurements to metric values. It targets professionals in construction, architecture, design, education, and field work who need quick, reproducible metric data. Core task is to produce a single, well-defined meter value from feet and inches inputs, with predictable precision.
Core Logic & Features: The tool uses a multi-field input model (feet, inches) and a dedicated calculation path. Required features: input validation (feet >= 0; 0 <= inches < 12 with decimals allowed), conversion formula, and formatted output. Optional/advanced: support for fractional inches, configurable decimal precision in downstream export, and batch use by repeating inputs.
Inputs & Outputs: Inputs are feet (integer) and inches (float), inches range validated; outputs are meters (float) with a fixed format. Example: 6 ft 2 in → 1.8796 m.
Algorithms & Calculations: The total inches are computed as feet * 12 + inches; meters = total_inches * 0.0254. The conversion uses the exact inch-to-meter factor and rounds to the requested precision for display.
Error & Edge Cases: Invalid ranges (negative feet, inches outside 0–11.99) produce validation errors (without UI text); missing inputs are flagged; non-numeric inputs are rejected. External data unavailability is not applicable.
Industry/Region & Localization: Units follow international standard conversions (Imperial to Metric). Uses SI unit meter; supports US customary measurements. Locale considerations include decimal separators and numbers in en-US style.
Assumptions & Exclusions: Assumes inputs represent linear length only; excludes weight, area, or volume conversions; not connected to devices; no rounding beyond display precision unless specified by downstream tools.
