My first Journeyman couldn't read a tape measure any closer than a 1/4". Anything in between the quarter marks he'd count as itty bitty marks. Like... 3 itty bitty marks past 1/2". That was a real pain in the butt. He had just recently learned that he could see the back of his head with 2 mirrors once he began to let that 70s barber style his hair instead of keeping it in a forever summer cut.I grew up using both metric and imperial measurements so I have no issues using either. Many many years ago I had to laugh when an apprentice, who was a real smart arse, read out a measurement and said three eights sixteenth at the end of it because he couldn’t relate to seven sixteenths. Luckily he wasn‘t dealing with 32nd’s and 64th’s.
They are doing percentage angle instead of percentage grade?! Wow, that is silly. Not many roads go due vertical...Back when I was young and lived in the UK the road signs to denote a hill were expressed as a ratio i.e. 1:5 and we all understood what they meant. Now the trend is to nominate the steepness as a percentage of the angle from horizontal to vertical i.e. 15%. Why anyone would want to make it more complex for those that have enough issues grasping the steepness of an incline I have no idea. I can‘t imagine many drivers relating to a sign that indicates a hill as a percentage of 90 degrees .
3 would be close enough for my first journeyman.How many shakas is it to a meter?
He must have had very big hands. I'm about 5 shakas to a meter.3 would be close enough for my first journeyman.
U.S. Interstate System has used % of grade since Eisenhower and he did pretty much win the war.They are doing percentage angle instead of percentage grade?! Wow, that is silly. Not many roads go due vertical...
Chains are a surveying measurement. 80 chain to a statute mile. 4 Rods to a chain, and 100 links to a chain (about 8 inches each link).Chains
YESS, odd indeed. I had the same experience when driving in Ireland. They seem to allow ridiculous fast speeds on roads that could not ever handle those.The speed limits in Ireland had nothing to do with the safe speed for the rode you were on (a subject for a different discussion), but I could get my head around it
The British are more middle left wing actually. Not that the choice of government shows this but corruption is everywhere in politicsWell, the UK has been mostly metric since the '80s (changed money units in the early '70s) and there's not many people nearly as conservative as the British.

very true. so once again, I am not dissing things.Sometimes there are questions about wire size. You can't just expect everyone to use mm² wire sizes. People need to use the wire sizes available to them. No one in the USA is going to go to any store and find metric sized wire. It's all AWG (american wire gauge).
can second that. Most of the technical literature, research etc is written in metric.Americans in technical jobs tend to use both
lol fraction inch are the most annoying part about the imperial system. Millimeter and Micrometer are just so easy.quarter marks he'd count as itty bitty marks.
I think no one ever came up with anything smaller because nobody at the time of settling on those units possessed the body part or tools to identify anything smaller.Couldn't have someone come up with a unit smaller then inch? like Thumbnailthick and some random number one inch = 35 thumbnailthick fractions are just a so error prone.
are you sure? construction yes. All inches and super complex fractions. But take a look at your food nutria label. It should be metric yes?Outside of construction and food stuff
I like the way a thousand liters is based on the volume of a cubic Meter. Those liquid tanks with the cages around known as "Totes" come in a few sizes but the 280 gallon size is also a thousand liters and based on a cubic meter1 Inch = 25.4 mm by definition; presumably so one can use a 127 tooth gear to thread metric threads on a lathe with a fractional inch lead screw.
1 Pound (mass) = ~1/2.202 Kg. This is a bone of contention since a pound is force and a Kg is mass. This conversion only works with an assumed gravity value. Almost nobody wants to use Slugs unless they are actually dealing with mass. In that case, I bet they use metric.
1 Pound (force) = ~4.448 Newton. I will admit that most Americans have no idea what a Newton even is.
Completly off topic. I know the best cup size.Or were you refering to cups, spoons and what have we?
like I said, Metric is common exceptions are: construction and anything centered around food. I would consider baking related to foodare you sure? construction yes. All inches and super complex fractions. But take a look at your food nutria label. It should be metric yes?
Or were you refering to cups, spoons and what have we? Yes I keep struggeling with those units as I try to learn how to bake good cuisine by America's best online chefs.
A inch is the width of a average thumb, that is true. Yet, even in the antique (3000 years ago) - Clock Maker and Locksmith used smaller instruments and somehow got that working. The romans had their aqueduct on inclines as little as 1mm per 15m and to keep that accurate over hundreds of miles - you instruments must be more precise then a finger width.nobody at the time of settling on those units possessed the body part or tools to identify anything smaller.
And on ships a Shot of Chain is 40ft, even on metric ships.Chains are a surveying measurement. 80 chain to a statute mile. 4 Rods to a chain, and 100 links to a chain (about 8 inches each link).
