There are 25,400,000 nanometers in one inch.
nano is 10 to the power of -9, micro is 10 to the power of -6 and so number of nano grams in i micro gram is 10 to the power of -6 divided by 10 to the power of -9, giving an answer of 1000
120 seconds.
120, if it is a polygon.
I'm not sure where you are getting your information. Capacitors come in a large range - nano farad to several farad. The higher the farads, the bigger (in general) the capacitor will be. For example, amazon has a 1 F, 20 volt cap for ~76.00. I would consider this to be "generally available in the market". If you want a 1 farad cap for 120 volts, it's going to be substantially bigger than this one (20 volt is ~5 lbs.).
farad is the unit for capacitance in SI system. If one volt is developed as one coulomb charge is placed then capacitance has to be one farad. But one farad is enormous large one so practically speaking we use only micro farad, nano farad and pico farad. They are respectively 10-6 F, 10-9 F and 10-12 F
nano = 10-9 pico = 10-12 nano / pico = 10-9 / 10-12 = 103 or 1000. The prefixes mean the same thing (the same numerical multiplier), whether they are used with seconds, meters, Farad, or whatever.
The prefix for "billionth of ..." is "nano...".It's used for tiny fractions of several different units, including meter, second, farad.
Capacitors are built to different specifications depending on application. The higher the capacitance the more charge the capacitor can store.The capacity to store electric charge, when a voltage is applied. Measured in Farad = Coulomb/Volt. In other words, if for every volt applied the capacitor stores 1 coulomb of charge, it would have a capacitance of 1 farad. In practice this is a huge unit, and the capacitance is usually expressed in micro-, nano-, or even pico-Farad.
Farad
The prefix "p" means "pico" - a millionth of a millionth of something. Therefore, 100 pF is 100 x 10-12 Farad, equal to 10-10 Farad. Since a Farad is, for most practical purposes, an extremely large unit, prefixes like micro, nano and even pico are often used with it.
500K is 500 000 µ Farad so it's ½ a Farad
A Farad is the electrical unit of capacitance. Many commonly used capacitors (also known as condensors) are measured in micro-Farads (μF). A micro-Farad is one millionth of a Farad. To convert from micro-Farads to Farads, divide the micro-Farad value by one million. 2 micro-farads = 0.000002 Farads.
