650B = 584mm diameter wheel
700 = 622mm diameter wheel
Brake shoes need to reach another 19mm (38/2), so that's why if you have brakes now with, say, fairly common 40-45mm reach, the Dia Compe/Weinmann 610/750 models will give you plenty of max reach (61mm or 75mm), as will several others currently available.
