If you're here, then like this blog's author, you are a stickler for detail.

We use “nanometre” as the spelling, rather than the Americanised “nanometer”. “Nanometre” is the spelling used and recognised across the world as the SI unit of one millionth of a metre. (The Bureau of International Weights and Measures sets the spelling). Since we are based in the , it is appropriate to use the nanometre spelling.

So here we use nanometre, which is a small measure of distance, rather than nanometer, a device for measuring nano's.

I ask for forbearance from our American cousins for the inclusion of additional “u”‘s, conversion of “z” to “s” and the reversal of the last two letters in “nanometre”.
