Question about Gate and LUT

Hi there, I have a question about the LUT and Gate. Is there any relationship between the Gate count and LUT count? Say 10 Gate equals to 1 LUT, someting like this. Is there exsit a experience...

an LUT of 3 inputs can decide output of 8 possible input patterns (000 ~ 111):

Then you can make a good guess from that if you try implement the table in logic gates.

The final gate count will depend on pattern of output, your gate choice, your skills to design and reduce your logic using boolean algebra or karnaugh mapping.

So I believe in short there is no standard answer to your question.
