because i am an artificial being created in one of those secret bases of ukraine. that was overtaken by russia than flew to tanzania in order to be protected from all the other goverment but i did run away to south african republic than hidden myself away in united arabic emirates than for some reason woke up in poland and than got myself to usa and when i was bored with messin up the banking system i arived to uk
so using both imperial and metric system is no difference to me but makes a difference to much of normal world who use metric system
