Aperture & Iphoto problem

[Skibsted]

So I have quick question here:
When I first got my mac I used Aperture for managing my photos. I just recently switched to iPhoto cause its faster and I don't need all the fancy features in Aperture.
I have dragged all my photos from aperture into iPhoto and I have checked the "copy items to the iPhoto library".

Why is my aperture photo library almost 11GB and my iPhoto library is only 1GB?
I want to just delete Aperture (and the aperture library) from my computer but I'm unsure of whether I'm going to delete anything in the process.

Can anyone help?

Thanks in advance

Just a guess but are your Aperture photos in Raw and when copied to Iphoto copied over as jpeg?

kitmos,
How do I tell if they are "raw"?
Yes, when I drag a picture from Aperture to iPhoto the format is jpeg.

Looks like you only copied the preview images. You can check. From inside iPhoto looks at the image info. How many pixels wide and tall are they?

In aperture's terminology, what you need to do "export the masters".

ChrisA:
A random Photo in iPhoto is 6.1mb
The dimensions are
Width: 3.264 pixels
Length: 2.448 pixels

What does this tell you?
