The 10 uF marking on a capacitor indicates its capacitance, which is the ability of a capacitor to store an electric charge. The unit of capacitance is the farad (F), and a microfarad (uF) is one-millionth of a farad. So, a 10 uF capacitor can store 10 millionths of a coulomb of charge.
What does 10uF mean on a capacitor?
Answer: So ultimately, 1 farad is so large because the base units are so large, at least relative to the sizes of electronic components nowadays where we fit billions of transistors onto several square millimeters. Because it fits in with all the other (SI) units we have. 1 farad is 1 coulomb per volt.

A Farad is huge - being a capacity capable of holding 1 Coulomb ( another huge value ) per volt of charge. Capacitors are typically rated in much smaller units ranging from millifarads down to picofarads. A farad-sized capacitor would be the size of a large can of coffee, perhaps even larger.

The smallest unit of capacitance in typical electronic circuits is about one picofarad (one trillionth of a farad)—-though microwave circuits use even smaller values.
What is the smallest unit of farad?
Farad is the unit of capacitance. A capacitor has a capacitance of 1 F when 1 coulomb (C) of electricity changes the potential between the plates by 1 volt (V). Another way of saying this is that, when the voltage across a 1 F capacitor changes at a rate of 1 V/s, the result is a current flow of 1 A.
What quantity is farad?
We know that Capacitive reactance is given by the formula Xc = 1/(omega*c) where Xc is the capacitive reactance in ohms, C is the value of capacitor in Farads and omega is 2*pi*f where f is the frequency. So by using the relation, Xc = 1/(omega*c) = 1/(2*pi*f*c) we can convert farads to ohms.
