Multiplying a raster object

Hi community,

I have a raster object of a kernel density, where the linear unit is meter,
and when I plot it it gives me very small density values (units per sq
meter, I suppose). I figure that if I multiply it, say by a 1000, it will
give density values in units per sq km. It looks good on the legend, but I
wonder: is this a correct thing to do? I wonder this because when I add the
values of the raster it does not add up to the number of points in my
original ppp object from which I created the density.

Thanks,

Tada
