# Length Conversion

Early units of measurement date back to 3000-4000 BC. Many measuring systems relied on parts of the body as the standard. This caused a range of variance within different groups of people. A yard was described as the distance from the center of the chest to the fingertips of an outstretched arm. Obviously someone with longer arms would have a greater length than someone with shorter arms.

During the French Revolution a standardized system of measurements emerged. It was a decimal system based on the meter. Over the next several centuries the metric system was widely accepted and implemented across the globe, and has developed the International System of Units as the current standard for measurements. The United States, however, continues to use the US customary units such as: the foot, yard, and mile, even though Congress authorized the use of the metric system in 1866.

These two units of measure are used interchangeably all over the world, so it is imperative that we be able convert between the two units. This extremely difficult without the use of a calculator. The metric systems works on a decimal basis, but the US customary units do not. It is easy to remember that there are 1000 meters in a kilometer, but how many feet are in a kilometer? How many inches in a meter?
