Are you at least familiar enough with the metric system to convert basic units like kilogram, meter, liter to imperial units in your head? Doesn't have to be exact, just ballpark.
Metric is easy. Everything breaks down into 10.
Imperial lacks logic imo. Why are there 12 inches to a foot but 3 feet to a yard?! Weight makes even less sense. I don't understand why some insist on keeping this nonsense when even engineers and architects here use metric.
I can ballpark a few things. Never really used metrics except in high school chemistry. When a conversion is needed now, a smart phone makes it simple and quick.
Yes. A meter is about 3 feet. 1 gallon is about 4 liters. I think 1 mile is about 1 1/2 kilometers, so yeah, I could ballpark most of them.
Down in small numbers, I can convert from inches to mm. Its handy when your missing a wrench from one set, but have it in the other
No, they’re just random nonsensical terms.
It’s the reverse for me. Metric is easy and everyone uses it but the US. So, I’m trying to convert metric into feet, inches, miles etc.
What’s 8’ 5 3/8”?
2.6 something, I think. I hate math
I’ve done a lot of building and woodworking and had problems with metrics. You get so used to fractions, inches and feet. My rulers with metrics have too many numbers.
There are apps for that. I use itunes.apple.com/us/app/convert-units-free-best-unit-converter-currency-conversion/id337224035
After a couple deployments, everything in KMpH and the gym full of 20 kilo plates (and maybe drinking a few 2 liters along the way), I have a rough idea.
Yep. I grew up using metric so I can use either one.
Definitely. You can do speeds in your head by just remembering 25=40 or 62=100. Distances the same, or 1.6 to 1. Lengths as 30.5 cm per foot, 2.5 cm per inch, 39 inches per meter. 3.8 liters per gallon. 2.2 pounds per kg. You can do temperatures by remembering to add or subtract the initial 32, as necessary, and the difference above/below freezing is 1.8 to 1 (easier as 2-10%). They’re all pretty simple, but the easiest way is to just stop doing conversions and remember 25 is heavy to carry, anything over 25 is too hot, anything below 10 is getting coolish, over 150 is fast, below 50 is slow, and 10 is close to the limit of "walking distance".
MPH yes, because I've driven in Canada extensively. All the other stuff, hells no.
Yes. Also dollars to euros and pounds.
I can do most of those calculations easily.
Probably the hardest is conversion of fuel efficiency from miles to the gallon to liters per 100 kilometer because the division is switched.
I know these 4 calculations. Anything between them or high/lower I can triangulate for an approximate number.
8 L/100 KM = 12.5 KM/L = 29 MPG
7 L/100 KM = 14.3 KM/L = 33 MPG
6 L/100 KM = 16.7 KM/L = 39 MPG
5 L/100 KM = 20 KM/L = 47 MPG
Notice the MPG changes by 4, 6, 8, it’s not linear (math I know) but something to remember.
I used it for over a decade in the Field Artillery. Those conversions are almost second nature....
I’m better at having an idea of approximate size comparison between metric and standard hardware sizes
Funny. A Canadian asked me a question...."we were doing 65mph." Was that fast enough? I said "indeed!" "About 100 kph?"
I'm well rounded. My parents did a good job 👍😎
I know the basics, 2.54 cm/in & 39.37in/m
I’m ignorant in grams.
Google is great.
If you want just an approximate, I came up with this rhyme for two units:
Meter is yard,
Liter is quart.
By imperial do you mean standard ?
No he means imperial gallons. Does anyone use those anywhere anymore? The Canadians did in the 70's.
I call our units gallon/inch/ounce etc imperial.
I call them standard or customary.
Yeah after living in France for 4 months I got pretty good.
Sure, it's not that hard. You can probably learn the basic conversion rules of thumb in less than an hour.
