maybe this will help

base unit one farad
millifarad = 1/1000 farad or a thousands of a farad (seldom used for
capacitors)
microfarad = 1/1,000,000 farad or a millionth of a farad

unfortunate the mixup of the prefixs "m"

In some measurements such as current
..001 amp is expressed as one mA m meaning milli
..000001 amp is expressed as one uA u meaning micro

So back to your original question - you need to ascertain the use of m
A 50,000 millifarad is a whopping capacitor and not likely
So it was probably 50,000 microfarads

Hope that helps

Thanks for the replies... So what does 50,000 mfd translate to in uF?
.5? .05?

If it says mfd it should mean mili-farads - not micro-farads.

Nobody uses millifarads, except maybe the boom car crowd. "mfd" or
more
commonly "mf", prior to (the 1960's) metrification/SI rationalization
meant Microfarads. And picofarads were "mmf" micro micro farads.
