result = value × (from-factor ÷ to-factor), factors anchored on meters

How does this work?

Every unit here reduces to its meter equivalent through an exact defined factor — the inch has been exactly 2.54 cm since 1959 by international agreement. Converting is therefore pure multiplication, never approximation, whatever direction you travel.

Metric steps are powers of ten while imperial units carry historical ratios (12 inches to the foot, 5,280 feet to the mile), which is why mental conversion between systems resists shortcuts and this calculator earns its keep.
