Do any other engineers like using US customary units more than SI units when measuring length?

Everybody uses whatever they find convenient. People have been assuring us for fifty years that metric would soon take over the world, but large parts of the world go right on using feet and inches and three different gallons and whatever they want. It is no problem at all to buy bead necklaces anywhere in the world because everybody measures the diameter in mm and the length in inches. And nobody finds that odd at all. If you go to a precious metals broker to buy silver it is weighed in troy ounces. But when you buy silver jewelry it is weighed in grams. Because people find that convenient. Gems are still weighed in carats. A carat is 1/5 of a gram, but absolutely nobody ever weighs gems in grams. Only carats.

Artists and designers prefer to use feet and inches because they are more concerned about proportions than ease of calculations. Every body knows how big a foot is and how it compares to a yard. Nobody knows how big 30 centimeters is or how it compares to a meter.

You get the same effect from digital clocks: sure, it's real easy to teach a kid to read the time from a digital clock. But he can't tell you if five minutes is a short time or a long time.

I'm a fairly ancient British electronics engineer and I use a mixture of units - whatever feels right. For anything to do with my work I use mm, cm or m as appropriate. Except that most IC pins are spaced at 1/10 inch, so I work in those if I'm laying out a circuit board.

If I'm sending a parcel it's measured in kg and cm. If I'm buying meat or measuring a room it's in pounds and feet.

For liquids it's litres, unless it's drinkable, in which case it's pints!

One thing I just can't get my head around is small measurements expressed in inches. 7/32"? I have to reach for my calculator to convert that into something sensible (5.55mm).

By the way, "US customary units"? Don't you mean imperial measurements? :-)

Well, before SI there was CGS (centimetre gram second). Grams were a bit small for most purposes. Whatever you do, some fundamental unit works out unusable unless you scale it.

I'll use inches if it make sense - old integrated circuits have a 2.54mm lead pitch (0.1") for instance. But I find it easier to visualize 3.67mm than 13/64", and I got messed up once when I wrote 2'4" and a supplier read that as 24".

I am not certain why the U.S. Does not use metric, however due to the fact that that the majority of the sector uses the metric process it might be shrewd for the USA to vary it. Travelers to different countries would have an easier time adapting to temperature, velocity, measurements, and many others. I am at a loss after I ask for the temp and humans tell me what it's in Celsius. The other man or woman that answered is right when she states that it might price a lot of money to alter it now, at least with street signs....

I'm an EE and when I was first exposed to SI units I didn't like them. However, I worked a lot with magnetics and electric fields. SI units for these areas are far better than US units, and I love them compared to useless US units. They are also great for thermal analysis and dynamics.
