Feet to Inches

About This Tool

This tool converts feet to inches using the standard imperial conversion of 12 inches per foot. It accepts decimal feet values and returns inches with numeric precision suitable for engineering, construction, sewing, and education. The design emphasizes deterministic behavior and quick, repeatable results for repeated measurements.
Conceptually, the input value in feet is multiplied by 12 to yield inches. The domain layer validates that the input is numeric and non-negative; non-numeric or missing inputs are rejected. The output is a numeric inches value, formatted with up to two decimal places by default to accommodate fractional inches when needed.
Who benefits: students learning unit conversion, craftspeople sizing materials, and professionals performing quick feasibility checks. Unique value lies in strict non-negative validation, consistent conversion factor, and straightforward readiness for API or batch usage. Core features include a single numeric input, immediate conversion, and deterministic output suitable for downstream calculations. Typical use cases include fabric sizing, material planning, blueprint checks, and classroom demonstrations that require reliable, repeatable length results.
