Metrication is the process of transitioning from traditional measurement systems, like the Imperial system, to the metric system. The metric system is based on units such as meters for length, liters for volume, and grams for mass, making it easier to understand and convert between different measurements. Many countries have adopted this system to promote consistency and simplicity in trade, science, and daily life. The push for metrication began in the late 18th century with the introduction of the meter and kilogram in France. Today, most countries use the metric system, while a few, like the United States, still primarily use the Imperial system. This ongoing transition aims to enhance global communication and collaboration.
