based on the requirements analysis were all met; this is
evident with the full agreement of all expert testers. e
major parameters (Eciency and Usability) were rated
by the pool of experts as Strongly Acceptable. e dif-
ferent parameters were ranked based on the weighted
mean to determine the best parameter the mobile system
has and based on table 4 that best feature the system is
its Usability. Although the mobile system was deemed
strongly acceptable improvements can be made so that all
parameters will have a perfect rating and for the mobile
system to be more resistant to errors and bugs. Overall,
the system has adhered to the quality standards of ISO
9126.

Grand Mean 4.63 Strongly Acceptable
6. Conclusions
Based on the System Development and Expert Testing,
the following conclusions were drawn:
1. e following features were successfully developed and
integrated into the system, as per results reected on
table 1:
a. A module for choosing the base number system to
the desired number system.
b. A component for capturing written text.
c. A module for showing the converted value.
2. e Expert Testing resulted in a grand mean of 4.77,
interpreted as strongly acceptable. is means that the
system adhered to all sub-parameters under the major
parameters Eciency and Usability. Furthermore,
improvements in the overall design and fault tolerance
are recommended to improve the results of the expert
testing.
