Making sure standard weights and measures are the same all over the world is
an important task. To trade internationally, a kilogram in Mexico must weigh the
same as a kilogram in Japan. In the past, countries set standards for weighing and
measuring individually. One English king declared a yard to be the distance from his
nose to his thumb egotistically. Weight was once measured in barleycorns, so
unethical merchants soaked barleycorns to make them heavier in water. Today, the
metric system is the worldwide standard, and the weight of the U. S. pound is based
even on the standard kilogram. In France, a cylinder is the world standard kilogram
made of platinum. Securely, this official kilogram is kept in an airtight container.
Nevertheless, losing a few billionths of a gram of weight each year, world standards
might eventually be affected. Hoping to find a permanent solution, scientists want
to base the kilogram measurement on an unchanging natural phenomenon.
