Darn. First try 11. I've never heard of zepto, yocto, deka, hecto, exa, peta. Should've got pico, deci and femto.

The two tiniest ones make me think of long-lost members of the Marx Brothers.

Always get lost at the extremes and have to try zetto, zecto, zotto, and so on. Got there in the end. I'm astounded that more people got femto than peta. Does no one deal with petabytes of data?

I deal with femto more than peta, but then I'm a biology student working with tiny little concentrations of stuff.

I think for a little bit of an extra challenge, the abbreviations should be removed. Good quiz nonetheless.

Towards the end, the more difficult ones all sound like Marx brothers' names.

17/20, although I was about to give up with 14 before I noticed the symbols were also given, at which point I remembered femto, and somehow pulled out atto and zetta while playing around with various things I though could be answers.

Nice one, but why isn't this in Science like the other SI quiz?

I'd say most people have never heard of the prefixes beyond 10^9 and 10^-9

You should accept zeta, methinks. Good quiz, though!

Technically there are since Jiggawatts was just a common mispronunciation of Gigawatts.
