Setting the correct scale for a scale bar

I'm using two coordinate systems to carry out my project;
1. WGS 1984 for the analysis
2. WGS 1984 World Mercator to display the output maps

The WGS 1984 World Mercator scale is incorrect for my area and want to apply a WGS 1984 scale to a WGS 1984 World Mercator map.

Does anyone know if this is possible?

Many thanks,
