My point has nothing to do with calculator use. My objection to your "logic" is that it's based purely on familiarity and the assumption that one must always start with some Imperial unit or other as the base.
It's simply a nicer and as well, a more natural measurement. The "foot" for example. Also the the foot being a dozen inches. The Imperial has more character. That is why when I sad above about the very tall young bloke delivering my stuff from the supermarket said when I asked him how tall he was he said straight out, 6 foot 8. Even though the metric system has been in Australia since about 1972, this young bloke at about 21 sure grew up with metrics but he did not say he was 203 cm, no, he went straight for 6 foot 8. The reason is simple, when you are that tall it is a very big feature of your character and to his mind deserves a lot more than 203 cm
