Can someone tell me the difference please Posted by melaine9 on Nov 23, 2014
i want to purchase some eyes for my puppet building.  But I have no idea about millimeters  Is the higher number larger or the smaller? For example 9mm vs 16mm.  I feel like a dummy for asking. I anyone can help it would be a great help.  Or what  size do you use in building.?

Nine millimeters is small. 16 is not quite twice the size.

Ah, when will Americans catch up?

If it helps, I use this site whenever I need to convert between metric and imperial. Just select what measurement you need, plug in your number, and out comes the conversion. http://www.digitaldutch.com/unitconverter/
I use it all the time.

No probs. There are lots of handy converters out there that I've bookmarked over the years. That's the one I use the most.

I have a friend who actually knows in detail why Americans won't switch to Metric, and is maybe gonna do a podcast on it sometime. I barely remember the details of what he said - but it sounds like it's basically some weird fluke of history, and not because non-metric really has any merits to it. (I have heard arguments, like how a base 12 system has more numbers in it. But I don't buy that, because converting between everything is such a hassle.)

Oh wait, I think this link explains it:

Basically, Congress didn't make it mandatory for everyone to switch over back when it was voted on, so nobody switched.
