		Given that typical conductances are in units of mS/cm
		then typical absolute conductances would be of the order of microsiemens, currents are in nanoamps, capacitance in nanofarads.
		Since currents are in nanofarads, let's see what the conversion factors are for the influx of calcium.

		Capacitors come in all shapes and sizes and are usually marked with their value.
		The unit of capacitance is farad, however, the capacitance of a capacitor is generally small and so standard units such as, microfarad, abbreviated, µF (1 µF = 10-6 F), nanofarad, nF (1 nF = 10-9 F) and picofarad, pF (1 pF = 10-12 F) are often used to denote the capacitance of a capacitor.
		Most capacitor values are measured in microfarads, nanofarads or picofarads.

	Capacitor
		A capacitor has a capacitance of one farad when one coulomb of charge causes a potential difference of one volt across the plates.
		Since the farad is a very large unit, values of capacitors are usually expressed in microfarads (μF), nanofarads (nF) or picofarads (pF).
		When the voltage across a capacitor changes, the capacitor will be charged or discharged.

		Furthermore, as clock gating techniques are used to save power, a large portion of the circuits are turned on/off simultaneously, which can introduce substantial transient switching noise to the power grid.
		The traditional solution for this problem is to include both on-chip and off-chip decoupling capacitors (100’s of nanofarads for on-chip decoupling is not uncommon) to reduce transient peaks by providing passive decoupling.
		Tighter noise margins in advanced processes require even more on-chip decoupling; However, with added capacitance, there is ultimately a diminishing return for adding more on-chip capacitance.

		The microphone is a piezoelectric crystal that has a capacitance of approximately 40 nanofarads.

	Michelle and Neil's Homepage - Amateur Radio Capacitor Guide
		The term " milliFarad " is not generally used, but IS a valid way of expressing a value; 1 milliFarad = 1 thousand microFarads, and so the smoothing capacitor in a typical power supply could be 10,000 microFarads or 10 milliFarads.
		Back in the early part of the century, capacitors were marked in values expressed in microFarads eg 0.047 uF (47 nanoFarads) and some of the smaller values such as 470 picoFarads would have been marked 470 uuF.
		Nowadays the trend is for markings in picoFarads using a code similar to the code used for resistors, but with digits rather than colours.

	Farad - Wikipedia, the free encyclopedia
		Since the farad is a very large unit compared to typical requirements in electronic devices, values of capacitors are usually in range of microfarads (μF), nanofarads (nF), or picofarads (pF).
		The picofarad is comically called a "puff" in laboratory usage.
		F, for example, is usually written as 4700 µF. North American usage also avoids nanofarads; a capacitance of 1×10

	Electrical element - Wikipedia, the free encyclopedia
		If a wire is then connected between the two plates, the charge will flow through the wire to balance the charges on the opposite plates--the capacitor is then said to be discharged.
		Some capacitors look like a cylinder or blob with two wires coming out one end, and are marked to indicate their capacitance (the charge that they store per volt) in microfarads (μF), nanofarads (nF) or picofarads (pF).
		Inductance in a circuit is provided by components called inductors, which are almost always built from coils of wire.
