Question

A computer can do 1.8 gigacalculations per second. How many calculations can it do in a microsecond? ?

Answer 1

1 giga = 1,000,000 = 10^( 6)

1,000,000,000 micro = 10^( 9) micro = 1

Now start solving :

10^( 6) calculation = giga-calculation

1 second = 10^(9) micro-second

   1.8 giga-calculation / second  

= 1.8 * 10(6) calculation / 10^(9) micro-second

= 1.8 * 10( -3) calculation / micro-second



= 0.0018 calculation / micro-second.

---------------------------- ----------------- ----------------

NOTE :

In engineering we never use suffix like micro in the denomenator. We "should" use the suffix in the numerator only.. This is the law in the units !

Then the form given in the giga calculation per second is more preffered, however both are correct  :)

Answer 2

1.8x10^8 calc/s | 10^-6 s / 1μs | = 1.8x10^3 calc/μs = 1.8 kilocalc/μs

Answer 3

Divide 1.8G by 1,000,000.  You shouldn't be asking questions you either know, or can find anywhere
