Conversion basis
Every length converts through metres before the target unit.
Metric units scale by powers of 10. Inches use the exact definition 1 in = 0.0254 m, so feet, yards, and miles follow consistently.
Results display up to 12 significant digits. Very large or small values use scientific notation to avoid implying false precision.
Example: 10 cm ÷ 2.54 = 3.937007874 in; 1 ft = 12 in = 0.3048 m.
