Time of day does matter a bit, along with knowing if your 2nd flight is international. But generally, on weekdays it's 30 minutes on the BART to downtown SF, and trains run every 10 minutes or so. Some parts of the airport are a 5 minute walk to the airport BART station (A, F and G concourses), others require a 5-10 minute ride on the little airport train to get to the BART station. So you could be in downtown SF 50-60 minutes after walking off your plane, now 4 hours to flight. Spend 2 hours there, now 2 hours to flight. 45 minutes to get back, you have 75 minutes. No issues if it's a domestic flight, might want an extra 20 minutes if a bigger international flight which boards earlier.
