It is rather stupid that localization and language in web-apps are the same. They are not one, but separate classes. While US English is the dominant language in science, the old Roman Imperial measurement system is not. One should be able to use en-US for spelling etc. While using metric measure; ISO date format and in numbers the ‘,’ for thousand separator and the ‘.’ for decimal separator. So there is not 1 class, there are four: language; measure-system; dating-system and number-notation system.
