Measurement is the assignment of a number to a characteristic of an object or event, which can be compared with other objects or events.
1 million is 1 x 10^6
1 billion is 1 x 10^9
1 trillion is 1 x 10^12
So 12 trillion miles is 12 x 10^12 which converts to 1.2 x 10^1 x 10^12 = 1.2 x 10^13
Not true, you should change your rule to include the exception
