Why use imperial units when metric is easier?
Imperial units (feet, pounds, gallons) are traditional in the US, UK, and a few other countries due to historical reasons. While metric (meters, kilograms, liters) is easier for calculations and used globally in science, imperial remains common in daily life, construction, and commerce in these regions. Many industries require both systems - international trade, aviation, and manufacturing often need conversions between imperial and metric units.
