Interpretation:
The correct conversion factor for solving the problem “
Concept Introduction:
Measurement is the measure of quantity, capacity, dimensions or extent of something. Mass, length, pressure, temperature, volume, time and concentration are some common type of measurements. English system and metric system are two types of measurement systems that are in use in the United States. Measurement wise both English system and metric system are precise. There are instance where measurements from one system has to be changed to their equivalent in other system. This is called the conversion factor. These conversion factors always appear as pairs. For example
