if capacitance is mentioned in F/g then how to calculate total capacitance

What is F/g? I am not familiar with that expression and have no idea what connection it may or may not have to capacitance.
In mechanics F/g could be interpreted as a way of defining mass, as the force exerted on a small object by a large one, divided by the acceleration of gravity.

Iti s specific capacitance. I am not completely certain but I don't think it is possible to use specific capacitance alone to decide the total capacitance of a practical device.

That is a new concept. what is specific capacitance? If so what is the reference?

 

Farads per gram

Kudos! That one came out of left field. Checking datasheets on 0.1 μF 0402 ceramic bypass caps to see it they quote a weight.

It's particularly relevant to super capacitors and my understanding is that it give a capacitance per gram of a material for comparison against other materials to decide which has a higher chance of making a good cap.

To answer the question, now that we know what F/g means, You would multiply the F/g by the mass in grams to get capacitance in Farads.

I don't think it's that simple. The term F/g can only refer to the active material in a capacitor, that's only a percentage of the mass. There are also other factors that determine the measured capacitance of a practical device. At least that's how I understand it.

At least that product would be within a potential scaling factor.
