This is my best circuit

Ranges     |     0.1 in the display equals
--------------------------------------------------
100  mF    |    10 mF
10 mF       |    1 mF
1000 uF    |    100 uF
100 uF      |    10 uF
10 uF        |    1 uF
1000 nF    |     100 nF
100 nF      |     10 nF
10 nF        |     1 nF

Only select one range

After selecting the range and changing the capacitance of the purple capacitor close the switch on the bottom left .. 
To calculate again press Reset and open the switch and repeat

The display value is between 0 and 1 .. Multiply the value with the selected range to get the result
 
I could easly add more ranges .. But i wanted to make it simple .. But 1nF to 100mF will be more than enough

And also the display is just accurate to one decimal point (e.x it will tell you that it's 300 but not 350 or 370)
Again i could make that but it would be more complex

I didn't test lower values .. To calculate smaller capacances the frequency of the clock must be increased

I really like my circuit because it's very compact and easy + you can add more ranges very easly

I don't know if this will work in real life  .. If you made it you will just have to change the resistors a little bit

Nice, needs a reset button

Yeah .. But i actually don't know how .. I could't make it .. It should discharge the capacitor and stop the clock .. If the clock didn't start at the right time it will get an error result

Just connect the reset to counters together, and add a logic button to reset your counters

I just have problem with the clock .. If the clock started at LOW then the result will be wrong ..
