your question title is about measuring boxes but if your actual goal is the example in the code then this is a very inefficient way to find the width of a space, that width is already available as a tex length it is fontdimen 2 of the current font.

There is nothing equivalent (that I know of), but you can implement your own (and by implement I mean copy from latex.ltx and change the syntax). I defined SetToHeight, SetToWidth, and SetToDepth, that do the same as the LaTeX2e's variants.
However, for the specific case of a space, you can use fontdimen2font, which will get the width of a space in the current font without the need to measure a box, thus it is expandable, so you can use in dimension expressions. I defined an expl3y wrapper for that as well:
documentclass[varwidth]standalone
