Metric and English are two commonly used units of measurement, which are widely used in different countries and regions. The metric system uses the international system of units as the basis, and the English system uses different units of measurement, which may be different in different countries and regions.

Metric units include meters, kilograms and seconds, and the conversion between them is relatively simple. For example, 1 kg is equal to 1000 g and 1 m is equal to 100 cm. Using metric units can make the calculation in different countries and regions simpler and more unified.

English units are more complicated. Due to historical and geographical factors, different countries and regions may use different units. For example, Britain uses different units from the United States, which brings certain difficulties to international trade and cooperation.

The conversion between metric system and English system is widely used in daily life and scientific research, such as length, weight and temperature. Therefore, it is very important to understand the conversion relationship between these units. In our study and work, we need to master these conversion relationships skillfully in order to calculate and learn better.

In a word, metric system and English system are important units of measurement, which are widely used in different fields and countries. Understanding the conversion relationship of these units is very important for daily life and scientific research, so we need to strengthen the study and mastery of this knowledge.
