Dear Mr. R:

Please, oh please! When are you going to get metric nomenclature correct and stop making up your own spellings?

It’s litres not liters and metres not meters.

We are located in North America, so we do use the North American spellings on our web site. We explain this on our page noting the slight differences between British and North American English. Many of the differences go back to before the Revolution. While I personally admire Samuel Johnson both as a writer and a lexicographer, he was a Tory so his dictionary never received very much attention on this side of the pond.

By the way, our Spell Checker that ships with our Grammar Slammer program has both British and North American options.
