Hmmm... I have lived with both systems of measurement my whole life. I have rarely had to do a conversion. Use both long enough and you will get a feel for it. Many people I know can use them interchangeably. Generally, I am not worried by being precise to the tenths, hundredths, or thousandths. That may be required for the Olympic judges or NASA engineers, but not in every day life. I know what driving at 100kms/hr feels like and I know what 100mi/hr feels like. (On most highways I will get a ticket doing the second one.) It's similar to learning to speak a second or third language. Many times there are no exact translations in the alternate language but you sometimes come close.
