I do find cooking easier in grams. Just put the bowl on the scale and add ingredients until it hits the number. No measuring cups to wash. But it would life changing if woodworking switched to metric. Doing any sort of exact math is annoying as hell. What is 12’7” divided by 4? How many 1/8” is 0.55 inches?? It is my own personal hell.
I was born in the US and have switched by myself. My brother thought I was weird until one day we went to the hardware store.
I needed to buy a 15/64 in drill bit, but they didn't have it. So then we thought, fine, maybe we can use the next closest size...
...
Except WTF is the next size up or down from 15/64??!!! Neither of us could figure it out. Internet wasn't great. Sales people didn't know. We left because we weren't sure what to buy.
In metric, it's trivial. 5mm drill bit, 4mm is smaller, 6mm is bigger.
After this, he stopped thinking I was a weirdo for using metric measurements. But he still uses imperial because murica.
Also, interesting, I learned that he thinks imperial units were invented by the US. I told him they were British units and I stopped caring about British units in 1776, but he didn't seem to believe me.
Super selfish reason but as an architect in the US, I deal with nice round imperial numbers all day. Door frames, typically 2”. Standard commercial door, 3’x7’. All the codes are based around imperial too. ADA door width, 3’. Masonry Dimension, every 8 inches. At this point, it would be hard to remember that ADA turning radius is 1525 mm (not the easy 5’…. And yes, I know that’s changing to 67” soon). There are literally hundreds of dimensions I would have to relearn. I suppose it’s probably for the best to switch over and rip that bandaid off, but damn, it would be a headache and take me much longer to review drawings in metric (in the short term).
The imperial system (of length at least) has a very human basis. An inch is the first joint of your thumb, the foot is your foot, the yard is one step, a stride is two (step left, step right), a mile is 1000 strides. Normal walking speed is about 100 steps a minute, so a mile is about 20 mins of walking
The problem is when they generalized these distances, they apparently used the biggest guy they could find... It still makes sense for rough measurements, but I already use metric for anything small or precise. Or fast - I don't even know what gravity is in imperial units. Kmph isn't natural for me, but I think I could get there...I like 60mph being a mile a minute, it helps me estimate, but i could get over it
Weight and volume? I already use metric for everything but my own weight, because screw that nonsense.
Temperature? I'd like something more human scaled for daily use, I've tried getting used to it but metric just doesn't click the same way. I like how Fahrenheit is roughly the livable range - below 0 is intense even with proper attire, and above 100 is dangerous even if you're adapted to it. It's not perfect, but maybe something like Celsius*2 for easy translation?
Anything not coming into contact with you, like cooking or cpu temp, would be better in Celsius though - things change around 100C
At the end of the day, I think it just makes sense to have more than one unit of measurement for certain things - one for human scale that is easy to grasp based on our bodies, and one for measurement.
It would be nice to say "I need like 10 feet of hose" and they give you 3.5 meters because it's understood it's an estimate, or you say "I need these boards cut to 2.75m" and they know it's a measurement and give it to you exactly that.
And I would not miss it if volume and weights were metric only - i can't tell you how many times I've converted teaspoons to ml or ounces to grams, maybe it's because I learned chemistry before cooking but holy crap is that so much more helpful
