The grid in Saudi Arabia works at 230 V and 60 Hz; the recorded sockets is Type G. No surprises on voltage: Saudi Arabia runs at 230 V, the same range as at home in the UK. 60 Hz rather than 50 Hz matters only for motors and timers, not for power supplies.
The same socket system is used in Qatar, Bahrain, Oman and Hong Kong, so one adapter covers all of them. Nearby but different: Azerbaijan, Armenia and Afghanistan – an adapter for Saudi Arabia will not fit there. In Asia, 11 of 50 recorded destinations use exactly this combination.
