As a Physicist who grew up in England I learnt both systems. When I came to the USA with its decimal monetary system (England was still on the old 240 pennies to the Pound) I learnt an often un appreciated virtue of the British System. The first time I went to tutor an inner city kid he asked me to help him with a base 7 math problem! I then realized that 1) we had never formally learnt different base systems in my English Math classes. 2) The reason was we already knew different base systems from working with them in everyday life! So I had no problem helping him with the problems:-)
