A. Length Conversion

Length is a measure of distance between two points. The metric system is based on the meter, with the most common units being the millimeter, centimeter, decimeter, meter, decameter, hectometer, and kilometer. The imperial system is based on the inch, with the most common units being the inch, foot, yard, and mile.
