Fellow American convert to the metric system. Converting, in my opinion, won’t get you very far in actually understanding the measurements. To this day, the conversion rate is something I have to dig through my memory for.
For me what helped with the temperature scale was breaking it into chunks based on what I would wear, 10°-15° would be a pullover sweatshirt, 15°-20° a track jacket, etc, which got me to stop focusing so much on the conversion. Eventually you just get a sense of these things, I think that most people can only really feel a difference in air temperature of about 1°C. 0° being the freezing point cutoff is super helpful for judging things like potential road conditions if it’s wet.
For distances I first got the sense of how far things were in kilometers by being a runner and knowing distances around my neighborhood as to how they lined up with running a 5k, 10k, etc. For meters, at my height and gait, my stride length is about a meter long. A little bit on the shorter side of things, but it still helped me get an idea as to what a meter looked like in physical space, even if it’s off a bit. Centimeters and millimeters are a different story. Hard to find perfect analogs in the world, but you’ll find something eventually. I think for example long grain rice can be ~1 cm in length for example.
The biggest lesson in my own journey and seeing a lot of people online talk about trying to do the conversion is that people get overly concerned with precision when first making the switch. If you actually think about most of our daily interactions with measurements, they’re much more approximate. For example, the difference between whether it’s 71°F or 73°F is rarely pointed out. The temperature is just “in the low 70s”. We say that something is “about 20 miles away” which is almost an implicit 7-8 mile range. I would guess 80% of the time, this is how we interact with the units we use, so focus on that. No one is going to get upset if they ask the temperature and you’re off by a few degrees C.
In terms of mnemonics like US kids get in school for some of these things, everything in the metric system is a multiple of 10 from everything else, which is what makes it great. Also remember that at room temperature, water’s density is 1 g/mL, so if one of capacity or weight is easier to visualize for you, it’s a shortcut to the other. Standard disposable water bottle in the US is 500 mL or half a kilogram of water.

If only metric time had caught on too…
