    hello

    i need some help and am confuse about it now..

    after calculating the math.. 1.67531519 x 10 power of negative 8.. if i change to nano it is 16nf???

    1.515761363 x 10 power of negative 10, if i change to nano is 15nf???

    what about changing to miro??? confuse with the 10 power of negative 8 and 10...

    hope help

    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.
