I have completed Engineering in Chennai. Currently, I am preparing for aptitude test from home in online. Daily i used to practice some set of questions in aptitude. But only issue is, I am not able to solve the problems when it is asked to convert from higher scale to lower scale or vice versa. I was frustrated to solve problems regarding conversion scale. By checking in Million to Billion Converter, I got clear idea about conversion.

Also, given conversion chart for all categories. From now on, I can solve all kind of problems regarding conversion. I have hope that I will get clear in competitive exams
