Hi,

I instinctively use "where" in this construction.

But I keep coming across postings

So on proofreading, of late, I often "correct" my error.

I'm thinking that in scientific formulas, the usage is legendary:

It seems very unnatural to substitute "in which" here.

Many thanks,

- A.

AvangiHow egregious is this "error"?In my opinion it's not an error.

I'm thinking that in scientific formulas, the usage is legendary:

Newton's Second Law Of Motion may be expressed as "F=MA," where "F" is the applied force etc.

It's not wrong.

Thanks, CJ and CSnyder.
