1.67531519 x 10^-8 = 16.7531519 x 10^-9 =17nF (rounded up)

1.515761363 x 10^-10 = 0.1515761363 x 10^-9 = 0.15 nF (rounded down)

1.515761363 x 10^-10 = 0.00015157 x 10^-6 = 0.00015157 uF

You had better practice this before test time until it's second nature. Count the number of times that you move the decimal point left and right. Larger units are to the left and smaller units are to the right.

I failed a test miserably once because an Angstrom is 10^-10 meters and not 10^-9 meters as I was using it. I deserved it though. Conversion problems cause satellites to crash.
