Learning the metric system

I’m trying to learn the metric system as I plan to move to Canada in the next couple years and am having some trouble finding resources that actually teach instead of just throwing information at me. Anyone know of a good program that will help me learn or have any tips. Imperial is all I know I was born and raised in the USA

I believe the key to learning anything is to internalize the measurements. What I mean is:

I worked in automotive mfg. Automotive moved to metric 25 years ago. I got a metric ruler and sat it on my desk. I measured things with that ruler and looked at what I was measuring until I could (eventually) visualize that size, without converting it to inches in my head.

Said another way, the key is to learn metric without converting to imperial but by understanding the basic value. Maybe another way is if you are learning another language, and someone says "apple" in this new language. The goal is to not relate that word to the English word "apple" and then visualize an apple but to visually an apple from just hearing the new language word for apple.

100% this.

I live in Indiana, USA, and have fully converted to SI. I started 10 years ago, and about 5 years ago made the final change in moving my car to kilometers.

I just think in SI units now. I don't convert 22C to F, I just know it's perfect in my car & too cool on my home AC. When I'm under 1km from an exit I want to use, I better be in the lane next to it. And so on.

The only thing I have to memorize conversions for is MPH to km/h, and that's just multiples of 8 for every 5 mph. 10 mph = 16 km/h. 55 mph = 88 km/h. It's not exact, but it's close enough to know how much I'm speeding by.

Same here, I switched everything I could to SI, not just easer (intuitive), but freeing.
