I think, (im not exactly sure), that a code such as 560 means 56 
picofarads. the first two digits are the first two digits of the 
actual value and the last digit is the number of zeros on the end and 
the answer is in pico farads. for example 103 would be 10nF (10000 pico farads)

i dont know what the 'k' means, but the 1kV means 1 kilo-volt.

while we are on the subject....

lets see if someone can explain the numeric code on very small (
physical size) caps....

for example  what is the value of a ceramic cap with     "560"  as
the only marking on it    or  "100K   1KV"

good thing I have a cap meter  but having to test 30 caps to find the
one I need is a pain...
some of the numerics dont even make sence to me from the meter reading test...
