# Whats the difference between uF and pF capacitor?

On a circuit it says I need a 4.7pF capacitor. Can i substitute this for something else? A uF? Whats the difference?

uF means micro farads. pF means pico farads. Pico and Micro are prefixes used to denote magnitude in measurements. Pico is .000001 times smaller than micro (10^-6 vs 10^-12) so no, you cannot use them interchangeably.

Capacitors are measured in the unit of capacitance, Farads, abbreviated F. A Farad is an extraordinarily large amount of capacitance, so typical capacitors have a capacitance of much less than 1 Farad. Rather than writing a decimal point and then 9 zeros in a row, we use prefixes as a shortcut (just like in units of length, e.g. meter, centimeter, millimeter, micrometer, etc.)

The prefix μ stands for micro, so 1 μF would be a microfarad. The symbol μ is the greek letter mu, but it pretty much looks like a u. The μ prefix implies that you multiply the value by 10^-6 (or 0.000001) to get the number of Farads. So:

The p in pF stands for pico, so 1 pF is a picofarad (pronounced peek-o). Pico implies that you multiply the value by 10^-12 (or 0.000000000001). So:

So, the short answer to your question is: No, you can't use a μF capacitor in place of a pF capacitor in your circuit.

• Uf To Pf

• Pf To Uf

My guess is that someone wrote mF and someone else wrote uF because they didn't have the 'micro' symbol on the keyboard. I hope you truly understand stand what capacitance means and how a capacitor "works". That's much more important !

• Somebody needs to teach you the metric prefixes

milli 10^-3

micro 10^--6

nano 10^-9

pico 10^-12

femto 10^-15

---------------

kilo 10^3

mega 10^6

giga 10^9

tera 10^12

peta 10^15

• uF = µF = micro F = 10^-6

pF = pico F = 10^-9

so uF don't match pF

u can't use a uF for a pF capacitor
