Conversion Formulas
feet = meters × 3.28084 · inches = cm ÷ 2.54 · yards = feet ÷ 3
Every value is first converted to meters (the metric base unit) using exact definitions — 1 foot = 0.3048 m, 1 inch = 0.0254 m, 1 mile = 1609.344 m — then converted out to the unit you need. Chaining through meters keeps all eight results consistent with each other.
