Length conversions are needed in construction, interior design, navigation, athletics, and everyday shopping — particularly when switching between metric and imperial products. Engineers, architects, surveyors, scientists, and runners regularly convert between units of length. Metric units (metres, kilometres) are the global standard, while miles, feet, and inches remain common in the United States and, to some degree, the United Kingdom.

Helpful tip

When measuring fabric, timber, or piping, always double-check which unit system your supplier uses before placing an order — a mix-up between feet and metres can be costly.
