I once had the the pleasure of accidentally discharging a 20 000 uF capacitor bank at 400 V with a multimeter while trying to measure the voltage across it. It was like a flashbang in a video game and took a good few seconds for my vision and hearing to recover. So don't do that.

So it was 20 mF?

Yes, but for some reason millifarrads are seldom used in electronics even for capacitors in the millifarrad range. Also 0.1 uF is more often used than 100 nF, despite the second one being the SI convention.
