Purpose of use
Aside from being a ham radio operator, I also build crystal radios.
Many of the designs require a 500pF air variable capacitor, but all I could find was 630pF.
So using your calculator, I was able to see how much capacitance I needed to add in series to bring the 630pF capacitor down to 500pF.

It worked great, my sincere thanks.

Purpose of use
Troubleshooting a power supply. Had a meter that only read a max of 10000uF. So, I had to series connect two of same to check filter cap value.
