Compute the absolute, exponential distance between two given prefixes:

16) kilo and femto ---> 103 and 10¯15 give a total absolute distance of 1018

 

17) milli and micro ---> 10¯3 and 10¯6 give a total absolute distance of 103

 

18) micro and mega ---> 10¯6 and 106 give a total absolute distance of 1012

 

19) centi and pico ---> 10¯2 and 10¯12 give a total absolute distance of 1010

 

20) nano and kilo ---> 10¯9 and 103 give a total absolute distance of 1012

 

21) deci and tera ---> 10¯1 and 1012 give a total absolute distance of 1013

 

22) pico and micro ---> 10¯12 and 10¯6 give a total absolute distance of 106

 

23) kilo and giga ---> 103 and 109 give a total absolute distance of 106

 

24) femto and centi ---> 10¯15 and 10¯2 give a total absolute distance of 1013

 

25) milli and centi ---> 10¯3 and 10¯2 give a total absolute distance of 101

 

Some people are always looking for rules to memorize to help them. Notice that when the two prefixes are from the same side (two negatives or two positives), the answer is the absolute difference between the two. If the two prefixes cross over (as in one positive and one negative), then it is the absolute sum.

OK, but what if the problem involves the base unit, as in "What is the absolute difference between nano and no prefix?" I guess the answer is that it doesn't matter because the absolute difference between 10¯9 and 100 is the same as the absolute sum.
