That thing about the queen and the princes etc. is silly and just gets in the way. Don't those people have anything better to do?

It could be useful at times, in my experience it's just two people trying to remember this strange ass poem and end up having to look it up anyways.
Get ruler. Hold your arm out 90degrees, Measure from the tip of your finger 1 metreacross your body, and rember where that Metre ends on your body. Then you always have a reference for 1metre
I was taught this to measure electrical cable. For me it's from my left shoulder bone to my right finger tips (or the right shoulder to left finger tips)
A person who buys some material, Thinks to themselves managerial, I could use grams or litres, Maybe even amps or square meters, At least it isn't Imperial.
Celsius:
0 is the phase transitiom temperature for water between solid and liquid under normal atmospheric pressure. 100 is the phase transition temperature between liquid and gas under normal atmospheric pressure.
knew about the 0 but not the 100, good shit.
Also, this one might be somewhat subjective since stuff can feel hot or cold depending on the person, but body temp is around 37C, with hands lagging behind a degree maybe.
Even a two degree difference is obvious, and helps with pets (cats have an internal temp of 39 and dogs of 37), and to a lesser degree, cooking.
I'm in Canada, and learning French in school actually helped me with fractional measurements since French is based on Latin.
Cent is 100 in French, so 1/100 meters is a centimeter
Mille is 1000 in French, so 1/1000 meters is a millimeter
Dix is 10 in French, so 1/10 meters is a decimeter (this is last because it's not super helpful since you never see deci- units in the wild outside of niche applications)
And for the powers of 10, we only really talked about kilo (1000) in school, but I was interested in computers since I was a child so I figured out mega, giga, terra, etc fairly early on.
Man you got some giant feet and sausage fingers lol
For length, for an average male one meter is about one large step with extended legs (useful for distances), or the distance between e.g. the left side of your torso to the end of the extended right hand (useful for estimating the length of rope or smth).
For weight, it might be useful that 1 liter (that's 1 dm3 but noone uses that except sometimes in scientific literature) is almost exactly 1 kg, and a typical cup fits 0.25 liter. A shot of alcohol is either 20 or 40 milliliters (0.02 or 0.04 liter) depending on where you are and what you order.
For conversions you just need to remember the base unit (e.g. meter and grams/kilograms) and the decimal prefixes. But you really only need milli (1/1000), centi (1/100) and kilo (1000) in day to day life. Then you simply shift the decimal.
Meter was easiest for me because it's essentially a yard (when eyeballing).
Liters are easy because the soft drink industry picked up on it decades ago as a way to get people to drink more soda. You'd buy cans and 6-packs, but nobody bought a gallon of soda. But they would, it turns out, buy a liter of soda, and as we got more obese as a nation, 2 liters. Liters of consumer drinks are really common, and so easy to visualize.
yard
Except in US handegg, do people still use yards? It sounds old-timey to me now. Normally, I either hear people talk in feet or miles, but never yards. Even in school (California), I vaguely remember hearing "X yard dash" when I was a little kid, but that definitely changed to "X meter dash" as I got older.
Huh. I don't really hear any units of length anymore, now that I think about it. Even the doctor measures my height in inches, not feet+inches.
I honestly don't know. I don't hear "meters" used at all, but the first thing that comes to mind about "yards" is the 2000 movie The Whole Nine Yards.
US football still uses yards, doesn't it? I don't watch football either. But I just checked a random football stats website, and it still uses yards to measure pro football stats, so... yes, I guess. A lot of Americans still uses "yards."
I was confused on the "cup" part because I wasn't sure if you meant like a typical drinking glass or the actual cup-customary measurement until I looked at it (another reason i dislike the measurement system...a cup of coffee is so damn vague at times). I'll definitely remember the torso one.
It's weird i know my measurement in both metric and imperial because when I was a child i learnt to play lawn bowls and all the old people measured everything in inches feet and yards, then when I became a mechanic there's the three spanner sets so I can do all those.
As for tips, I worked out my own pace count for 100 meters, and at my old workshop we had meter increments on the floor so you could work out what kinda goofy arse step you need to take for 1 meter.
Temperature obviously 0 is frozen water 100 boiling anything over 40 is damn hot outside but that one varies for person to person.
