For instance, a foot…is basically a foot length. So there’s this foot-measuring waddle some people do walking literally heel-to-toe to get a general sense of the space. An inch is kinda a finger width, etc (they’re all not perfect by any sense).
I’ve decided to just take the plunge and basically re-learn all my measurement systems because I’m seeing less and less of those being used. I started with just memorizing all the conversions but that’s literally just adding another step. Everything I own basically has settings to switch or show both measurements (like tape measures) so I’m just going to stop using Fahrenheit and the United states “Customary System” all together.
Any tips or things you’re taught or pick up on? There’s a funny primary school poem for conversion of customary liquid measurements,
Land of Gallon
Introducing capacity measurement to learners can be challenging. To make this topic more accessible and memorable, we can integrate creative and interactive activities into our teaching approach. Using storytelling, we can transform the sometimes daunting task of learning measurement conversions into a whimsical tale.
- In the Land of Gallon, there were four giant Queens.
- Each Queen had a Prince and a Princess.
- Each Prince and Princess had two children.
- The two children were twins, and they were eight years old.
Once students are familiar with the story be sure they see the connection between the story characters and the customary units of capacity measurement. If necessary, label the story pieces with their corresponding units of measure: queen = quart, prince/princess = pint, children = cups, 8 years old = 8 fluid ounces. You can reduce the number of customary units in the story based on student readiness. link
tl;dr looking for anything to remember the hierarchy and memorizing the metric and Celsius measurement system, sometimes explained in schooling or local sayings. (if I had an example for those systems I would give one lol).

I just learned some basic things and go from there.
A Ruler is Ruler 12 inches or 30 cm
A meter is roughly equivalent to a yard slightly more and both are like 1 big step
And then i just remember that theres 2.2 lbs per kg
1.6 kms per mile
10cm is long. don’t let anybody tell you otherwise
A small trick is to measure your own hand. How big is your fingers spread all the way? That will always be a good quick measure. Like this: 🤙and 🤘.
And for the hierarchy:
Kilo means 1000 of something
Centi means 1/100.
Mili means 1/1000.kilo + meter = 1000 meter. centi + liter = is a cube of water that measures
1 cm all around, that actually 1/100 of a liter. And 1/100 of a kilograms if it is water.
Edit: 1cm cube is a mililiter, because 10x10x10 its 3dimensional as Moody pointed out.Good idea with the hands, I kinda already had this with the other system (different methods though) so now I gotta do the new ones and sear that into my brain. I’ve always been interested in a tattoo like the myth busters guy with a ruler on his forearm but I like the hang-ten one and seems cheaper/less painful.
The military and doctors in the United States officially use the 24 time format, there is something to think about (when we talk about accuracy and adequacy)
I switched over all my devices to 24 hour - phone, computers, cars, etc. I even change the settings on my wife’s phone sometimes. It’s so much easier to mentally read.
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.
You mean the pint’s a pound poem? It’s not even right, you know. A pint of water weighs about 1.04 lb.
didn’t know that one, was referring to the Land of Gallon one. Get to prince and princesses then everything would get fuzzy, recently acquired a hot-plate thing with conversions on it so remembered even less of it till I looked it up again.
The land of gallon thing is ridiculous imho.
For temperature:
Water freezes at 0, boils at 100. Room temperature 20 degrees Celsius. Normal body temp 37 degrees.
Trivia of minus 40 Fahrenheit being the same as minus 40 Celsius.
Height and weight are usually still thought of in imperial (canadian here), so I think of myself as 6’2", instead of 188 cm.
Volumes and lengths and weights are related. One cubic cm is one mL of liquid. One cubic centimeter of water weighs one gram. One thousand mL of water makes one Liter, which weighs one kilogram.
2.205 ponds makes one kilogram.
Shifting between miles and km is a pain in the ass, given the 1.6 km per mile.
1 calorie is the heat required to increase the temperature of 1 ml of water by 1 degree

This is how I was taught it in school:
For daily use of temps, I found it best to just switch my apps and stuff to use Celsius. Then just made a point to take mental notes as to see what the current temps were on my devices. Especially when it was feeling too hot or cold. On days that felt nice, would see what temps they were and just kind of learned what ranges were between them (I tend to find 16-23C to be fine warm temps).
I can’t say exactly what the temps in Fahrenheit directly. But can give a range for friends and co-workers if they happen to ask me what the temps are outside (they obviously take the Celsius value as not helpful but they know I am going to give them). I can say that for me the “exposure therapy” of just using Celsius has been much easier than things like distance. I can kind of handle thinking of static distances, but I am not able to translate active things like speed.
We don’t really need any of those mnemonics because it’s a perfect systemMore seriously there is the “King Henry Died, Drinking Chocolate Milk” for the Kilo (1000) Hecto (100) Deca (10), Deci (0.1) Centi (0.01) Milli (0.001), but that doesn’t really help with measuring on the spot, aside from being able to get the prefix right.
There’s an average step being 1 meter, but thats less useful for people with shorter legs unless they want to join the ministry of silly walks.
One that I use often is converting meters per second to kilometers per hour. Because 1 meter per second is 3600 meters per hour or 3.6 kilometers per hour, you can actually skip the multiply by 3600 and then divide by 1000 and just multiply by 3.6.
But aside from time conversions, there isn’t really anything else that can help because it’s just moving the decimal.
Slightly related, you can tell how far away lightning is by listening for the thunder and counting the seconds. Sound travels at 346 m/s so every 3 seconds is roughly 1 kilometer away. But I suppose you can do the same for miles and count to 5.
Ty for the Mnemonic, definitely something I was looking for and even responded to someone else with the musical treble clef one. The thunder one will definitely help and something that can be passed onto kids (everyone basically knows the miles one). I’m gonna have to start compiling a list because all of you are awesome and there’s a lot of information on here.
Just wish signs in the states were posted with KPH as well but that’s extremely rare, I still associate maps with mileage and arrivals based on MPH so will be harder to transition that then anything else I imagine (120 miles away so about 2 hours on a hwy going 60 mph which is average for states).
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.
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.
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)
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
