typically years of experience refers to using the given technology or product as if you were working full-time using it (so about a minimum of 40 hours per week). I'm going to average it out to 20 hours since there is plenty of overhead in a 9-5 job. Assuming 50 weeks per year that's about 1000 hours per year. I'd say 7 years translates into 7000 hours of experience (this reminds me of the way pilots count experience as the number of flight hours).
