West vs East: Converting Results

[RedX]

Is there a way to convert results from the West Coast metric (1,-1,-1,-1) to the East Coast metric (-1,1,1,1) or vice versa (is this terminology U.S.-centric?)?

Since p_{\mu}p^{\mu}=\pm m^2, does this mean you can just replace a scalar like m^2 with -m^2, or add a negative sign to every contraction instead?

Does the Lagrangian, which is an invariant scalar, get replaced with a negative sign? What about scalar fields? Do they change sign? Spinor fields and gamma matrices? Vector fields? Phases (exponential of a contraction)?

Yes, it is possible to convert from the West Coast metric to the East Coast metric (or vice versa) by swapping the sign of all scalar quantities such as the metric tensor, Lagrangian, scalar fields, vector fields, and phases. Additionally, the gamma matrices and spinor fields must be replaced with their negative counterparts.
