What is the significance of 4.7 in electronics? Answered

Why are most electronics components available in multiples of of 4.7?  I've been noticing this a lot recently when looking for components, and it seems like an odd choice to be a common division, seeing as it doesn't divide nicely, and isn't a particularly easy value to work with.

If anyone knows why 4.7 is one of the most common values, I'd be interested to know.

Thanks.

It's part of the E12 series (as well as the E6 and E24 etc). It's the closest value to half of 10.

Thanks for explaining that, it was interesting to see how they come up with all the values.
