I generally assume every LukeSurl.com reader has a calculator to hand at all times.
Hmm,… Google Calculator doesn’t get this one.
Wolfram Alpha gets it:
The photon wavelength of a wave with a frequency of 25GHz is 1.199cm (or 1.2cm if you round up).
Is it spelt centimeter? Or is it centimetre?
Depends which side of the Atlantic you hail from. Despite being from the ‘centimetre’ side, I’m going to say this was *deliberate* and definitely was not *my fifth spelling error this week*.
So she’s an American and that’s your ingenious way of showing her accent in written form?
Right. Americans are the ones with accents. I believe you.
But because we made up the spelling, we get to write the r’s wherever we say they are. Although, at least in some British accents, the sound for the letter r doesn’t have an r sound in it at all, which seems a little off.
Metre = unit of length. Meter = measuring device.
I was under the impression that both spellings were correct, and that it also applied to theatre/theater, centre/center, etc. However, I personally spell it -tre. It just looks correct. (Also, spellcheck seems to think -ter is incorrect.)
Your spellcheck is British. Also, my spellcheck doesn’t know the word “spellcheck”.
Like others have mentioned both _are_ correct — somewhere. the -re suffix is used in British English, -er in American English.
