Concept explainers
(a)
Interpretation:
The given metric-English conversion is to be stated.
Concept introduction:
The metric system unit is the unit system which is accepted as the standard system of unit internationally. The nonmetric units are the common unit system which is not standard for the parameter to be calculated. The unit factors are calculated by taking the ratio of two equivalent measurement systems and these are used in unit conversions. The English unit system is common in United States and therefore it is used in the conversion factors.
