It is kinda sorta. We still buy 8 ft 2x4s, 3 inch nails and our rural roads are gridded in miles. Some things are in pounds and some in kilograms. Tape measures are usually Imperial on the top and metric on the bottom. Seniors you can speak to them in Imperial, young people you have to speak metric.
When my son was just a youngster, he asked me how long 3 inches were. I had to look it up in metric. because that was what he was taught in school. The only way I could tell what to wear outside with out translating to Fahrenheit was that if it was at 14 degrees Celsius and the sun was shining and there was no wind, I could ride my bike in a short sleeved shirt. Using that as the reference point I could tell whether I needed a coat or not when outside.
