2.21 Measurement Systems

Almost all countries/culture have their own traditional measurement system. On the other hand, SI/metric system is used internationally as the measurement system. There is degree of difference among usage of traditional system for business and daily life. For example, Japan is in metric system though there is a traditional system. The need for the traditional system is very low for IT application. In US, the feet-pound system is still used very commonly for daily life even though the metric system is adopted by law long time ago.
