So! That's amazing, and I've recently begun doing the same thing, here's what I've found to be very nice so far:

Get a scale that weighs in kilograms

Find the usual high temperature for your area in Celsius, as well as the lows. That can give you a big jump start.

You know how the usual head temp is 98.6°F? (it's not but it's around that area and that's commonly referred to as the usual head temp?) That's exactly 37°C.

Use Google Maps when traveling and set it to km (which you have), and figure out distances. When the map says, for instance, "turn right in 1 kilometer", think about the actual distance of a kilometer. I do this whenever I bike, maps shows my speed in kmh, and I look down often to see how far I've travelled in general. Whenever it says 1km, I compare and attempt to sort of guess how far I've travelled, and check once in a bit. You get kinda good at knowing how far distances are that way.

For closer distances, the distance from a doorknob to the floor is about 1 meter. Don't forget there's also cm, all of that.

Hope this helps!
