u stands for the Greek letter "mu" It looks like a u with an emo haircut, like your avatar. Mu has evolved into our letter m. uf = mf = microfarad. All are the same.

ARGH! wrong! surely:

u means micro = x10^-6
m means milli = x10^-3

that's 1000 times more!!! and would give you serious problems!

Normally, you'd be right, but when it comes to capacitors, they'll use m, u, and mu to indicate that it is micro. Millifarads would be quite large, as a farad is a huge measure.

I'm not sure why they do use m and u, but they will.

ah ok fair enough - that is a ridiculous system!
millifarads are indeed large (due to the ridiculously stupid size of the coulomb and amp and small size of the volt) - though they do make millifarad caps

Most people just cbf to type the letter mu in "µF" so they use mF (hold alt and type 0181 on the numpad, just fyi )

mF is an old way of writing µF, so some people still use it.

Also, an old way to write pF (pico Farads) is mmF (meaning micro-micro Farads)
