Centimeters to Feet and Inches Converter
Convert human height and room dimensions from cm to feet and inches. Features smart rounding for height (e.g., 5" 11") and architectural precision options.
About
Converting linear metric measurements to the imperial "Feet and Inches" format is more complex than simple multiplication. In standard usage, specifically for human height, decimals are rarely used. A person is described as 5ft 10in, not 5.83ft. This tool bridges the gap between raw data and social convention.
Accuracy becomes subjective depending on the context. For carpentry, rounding to the nearest 116th of an inch is vital. For driving licenses or medical records, rounding to the nearest whole inch is standard. This calculator provides specific "Height Mode" logic to handle the nuances of the 12-base system used in the United States and UK.
Formulas
The process requires modulus arithmetic to separate the feet from the inches.
