i want to design an interface has the function to do mapping from Entity object to Form object

public interface IFormToEntityMapper
{
   TEntity Map(TForm tForm);         
}

and vise versa.

public interface IEntityToFormMapper
{

       TForm Map(TEntity tEntity); 
}

i have the question if i should define these two functions in one interface and seperate them to different interface. if i put them into one interface, does that violate the SRP?
