The value is in between the letters, so 473 and 104 for those.
The first 2 digits are significant, the 3rd digit is the multiplyer, giving the value in pico-farads.  So for the multiplyer, add that many zeros to the significant digits.
So in this case, 47000, and 100000 pico-farads.
To convert to nanofarads, move decimal place 3 digits to the left.  You get 47 and 100 nano.
To convert to microfarads, you move decimal place 6 digits to the left (from pico).
So .047 and .1 microfarads.

  Yes, 100nF and 47nF.  They should also have a voltage marked on them.  Do not use them in a circuit that will exceed the voltage rating.
