mathematics - A word meaning "to set equal to one" in a mathematical application?

In physics or math, when you rescale a quantity to 1 you are normalizing it.



This might come up if you are finding a unit vector, for instance.



The term is also used when talking about natural units -- the idea of adjusting your system of units such that certain physical constants (such as the speed of light) are equal to one. From wikipedia:




A purely natural system of units is defined in such a way that some set of selected universal physical constants are each normalized to unity; that is, their numerical values in terms of these units are exactly 1.




You can normalize things to other than 1, but 1 is kind of the "default" I'd assume on seeing the word without context.



You probably wouldn't use this if you're just initializing a value to 1 in a computer program. If 1 is the natural default value for e.g. a counter, you would probably just use the word initializing, though.



The question is ambiguous enough that I can't tell which (if either) word is more appropriate.
