The bar, made of Platinum and Iridium that defined the length of a meter

A standard is a basis for comparison. Standards are made either by many people that agree on something, or if some organisation makes it so. There are many different standards in many fields of daily life. Standards are important so that correct comparisons can be produced.

Measurement[change | edit source]

The international system of units is a standard that is agreed on by most countries. In it there is metre (or meter). It measures length. There currently is a rod (made from a special material). This rod in Paris. The length of the rod says how long a meter is. So when people want to measure something, they compare it to the length of the rod. For practical purposes, the length of the rod has been divided by 10 (to get dezimeter), by 10 (to get centimeter), and so on. The iridium rod as it is called is the original measure of meter. Now new ways of measuring the meter have been utilized such as the measuring of certain types of wave lengths to determine an exact meter.

Music[change | edit source]

A standard in music is a song that remains popular, and is performed and recorded by many different artists. Such songs include "Yesterday" and "Something", written by members of The Beatles. Many of Hank Williams's songs have become standards in country music.
