The one that includes more than one type of unit is known as complex measurement.
Example
The simple measurement is the one that uses only one type of unit.
Example
If, for example, we want to convert
Converting from simple measurement to complex measurement
Two cases will be analyzed:
1.- Converting from minor units in to higher units:
In this case, it will be necessary to divide by
2.- Converting to lower units:
In this case it will be necessary to multiply by
Namely,
