I'm using FCEU if that makes a difference

FCEU runs at 60 FPS, unless you're in PAL mode. Then it's 50.
A hundred years from now, they will gaze upon my work and marvel at my skills but never know my name. And that will be good enough for me.

Precisely, FCEU runs at 60.09982293844223 fps when in NTSC mode and 50.00698089599609 fps when in PAL mode. But unless the exact value matters, listen to Ferret, not me.

Where do you find these numbers? I mean, the exact numbers for the fps. I find it pretty cool, even though I barely understand it ;)

In the usual way - reading the source code. 
int32 FCEUI_GetDesiredFPS(void)
{
  if(PAL)
   return(838977920); // ~50.007
  else
   return(1008307711);  // ~60.1
}
Divide those strange looking numbers by 2^24 (16777216) to get a more familiar looking ones.

Those exact values really came in handy for me. It allowed me to finally completely fix my audio sync issues when trying to make DVD video of FCEU output. Thanks a whole bunch, Bisqwit.
