## Homework Statement

The problem is I am wanting to know if the expression on the right hand side is dimensionless.

## Homework Equations

[tex]ds^2 = (1 - \frac{2GM}{c^2 r})c^2 dt^2[/tex]

## The Attempt at a Solution

Since the Schwarzschild radius is [tex]r = \frac{2GM}{c^2}[/tex] would I be right in saying that

[tex]\frac{2GM}{c^2 r}[/tex]

is dimensionless?
