Very True. I am of the age that still thinks in feet and inches and gallons, mpg and horsepower
Same for me in Canada. All my thermometers read in degrees F. I calculate my fuel consumption in mpg (without a painful conversion litres per 100 km don't mean anything to me). I measure everything in feet, inches etc. I've set my GPS to read in mph and miles. Everyone I know uses acres not hectares in conversation. Just checked the real estate ads in the local paper in the county where I grew up. All pertinent references are in square feet and acres. Not a single mention of hectares.
This will change with time I suppose. Now the younger clerks at the deli counter will sometimes give you a weird look if you order in lbs. The grey hairs just smile and nod knowingly. But many people in countries that went officially metric many years before us still understood and used non-metric units in everyday life for generations after conversion. My doctor may use centimeters for my height and kilograms for my weight but my young grandchildren will tell me how tall they are in feet and inches and how much they weigh in lbs. And when they want to know if the pool is warm enough to swim, I give them the temperature in Fahrenheit (it just sounds too cold to say 28 degrees C).
