I like celsiusscale for temperature.

0 is when water freezes and 100 is when water boils .

So in the winter i know if its below zero the roads ( and my car ) is icy .

And the size of the degree is the same as in the kelvin scale its just the zero point thats moved.

But you get used to anything :)

I would slowly go crazy without the metric system in my day job where electrical motors provide power in kW and Nm of torque ( Nm=W/s=Joule )
 
I know that metric is better for small scales that require precise measurements.
That is not something that is useful to me on a day to day basis.
Larger units are handier.
My partial college payments included doing machinist type grunt work. All my "micrometers" and all the machinery were all in denominations of inches but NOT fractions -:mad:- , as is commonly used in non-machinist measurements.
As such, I can relate to a "thousandth of an inch" [don't you dare call it a 'milli-inch'] much more readily in my mind's eye (re: mks).
Yet, measurement units of micro-meters and nano-meters also make sense.
Audio/video/RF work has made me appreciate the power of logarithm, when very "larger units", (as well as, very small ones) need to be handled.
Handling different numbering systems/units is equivalent to being multi-lingual; though, many of us cussed-out logarithms during college.:rolleyes:
 
Logarithms were needed since Noah's time after the Great Flood receded. All the animals were told to go out and increase and multiply, but these two snakes said that they could not do that because they were adders. Noah had to invent logs so that they could multiply by adding.

and then there are Whitworth nuts & bolts. Same threads as Imperial, but the heads are not metric or simple fractions of an inch.
I hope the history never repeats itself for them.

OT?
A strand of human DNA is 2.5nanometers (nm = e-9m) in diameter.
An ångström is a metric unit of length equal to 0.1 nm.
Atoms can be anywhere from 0.1 to 0.5nanometers in diameter.
Silicon has an atomic radius of 0.11nm, which is smaller than that of Gallium (@0.122nm).
Graphene (a 2-D/monolayer, honeycomb lattice that is an allotrope of carbon) has a molecular bond length of 0.142nm.
SOTA IC dies are at <3nm level, currently.


Moore’s Law states that, "every eighteen months, the number of components that can exist on an integrated circuit doubles."
Oh, Oh!:eek:

The three main temperature scales are easy with the right mnemonic.
The right mnemonic:

I remember the days when stock prices were quoted in eighths. Now decimal points to the penny.

I remember the days when people used to bend down to pick up a 25cent piece... but now we worry about global warming by expanding energy by bending down.:rolleyes:

I mean, the Ark was made of logs, wasn't it?
:cool:
