## Homework Statement

In the usual units where c=3x10^8 m/s and g=10m/s², what is g in the units where c=1?

## Homework Equations

## The Attempt at a Solution

I said, let's redefine the meter like so: [itex]\tilde{m}:=3\times 10^8 m[/itex] so that now [itex]c=1\tilde{m}/s[/itex]. And then I calculated g by substituting m for [itex](3\times 10^8)^{-1}\tilde{m}[/itex]... but is this what the question is asking? Because I might as well have chosen to derefine the seconds and since it is s² that pops in in the units of g, the answer would have been different. And the question seems to talk like there is only one answer: "what is g in the units where c=1?"
