No, not really.

Connection tracking is more related to TCP states. Obviously with
keepalives off, every request requires a new TCP connection, so
indirectly they are related through the TCP states.

384 bytes per connection (may be slightly different depending on
your kernelversion - see /proc/slabinfo, ip_conntrack entry) +
a couple of bytes per hash (I think 8 bytes) * hashsize (determined
when ip_conntrack is loaded)
