Five a day

I was just reading this critique/discussion of the Government's "Five a Day" fruit and veg scheme. I wanted to have a look at what the government considers a portion of each type of fruit and veg.

So I put five a day unquoted into google and it came up with the following :

five a day = 5.78703704 × 10-5 hertz

A brilliant bit of maths there from Google calculator. Do you eat portions of fruit and veg at 5.8 X 10-5 hertz?

Oh god. I'm the world's biggest nerd.
