Why is feet-and-inches better than meters for stating height?
In the US, height is almost always given in feet and inches, while most of the rest of the world uses centimeters or meters. Converting to centimeters rather than meters is often more practical because heights then come out as whole-ish numbers like 178 cm instead of awkward decimals like 1.78 m. This converter handles the feet and inches together so you don't have to split the calculation.
