nonstandard and standard measurements...
SI units
The English system and the metric system.
95 percent of measurements are less than 2 standard deviations away from the mean, assuming a normal distribution.
Actually, about 3 countries use non-standard measurements - the SI is the international standard.
You should convert metric measurements to standard US measurements when you need to communicate with someone who is more familiar with the US system, or if the specific context or requirements you are dealing with call for the use of standard US measurements.

Standard measurements can be useful for having a set scale that all objects can be measured by. It allows for a common standard by which to judge objects.
Tes, the end standard is easy for alignment with the axis of measurements.

I believe that standard measurements for a Euro Sham are 26" x 26".
Standard units are more commonly used than non standard units. Also, many of the conversion factors, such as the Universal Gravitational Constant or the Speed of Light, are in standard units and, if your measurements were not in appropriate units, you would need to convert.
Standard measurements are rather like the standard meanings of the words that you and I are using to communicate with each other. If a word has a standard meaning, then when I use that word you will know what I mean. If I use a standard measurement, then I can tell other people what I have measured and they will know what the measurement means.
