I'm trying to calculate area for a raster file which contains 2 layers (0 for unsuitable habitat and 1 for suitable). It's been calculated successfully but I don't know what is the unit of the calculated values.

Calculated Area for 43873037 counts:365608.662141 and for 3241800 counts: 27015.001513

Spatial reference: WGS84_world_Mercator, Linear unit: Meter, Angular unit: Degree, Cell size:0.0083333338, GRID format
