Help! how do i scale a photo?

Question

i have a wallet that has a part where i can put a photo in it, i have this picture on my computer which i love and the dimension is 640 x 480, but the slot in my wallet is 4cm width by 7.5cm across, does anyone know how to rescale the image, as i don't know what 640 x 480 actually means (cm?) and where i can print it as a photo?
