Usefulness of rem-calc() in SCSS/LESS

[zearle]

I was wondering if someone could tell me the use of rem-calc(). I see this pretty often and I’m wondering if it’s just a way for people to get comfortable using relative units while still being able to use pixel values? Doesn’t this kill the usefulness of it because if you change your base font size, for example, rem-calc(22) will automatically adjust your final rem value? So why not just use pixels? Or if you want relative units, use relative units?

Rem-calc is a Foundation sass function that converts pixels to REMs, so you can still think in pixels and end up with scalable em.

rem-calc(10px); // 10px will be converted to REMs
