For writing or typing distances in metric we use m (meter), or cm, mm, km. For English (I guess) distances we use " for inches and ’ for feet. Is there a symbol or suffix for our friend the Smoot?
It’s in and ft too.
So, what is it for a Smoot?
If you are an old-timey surveyor then you can use abbreviations like “[such-and-such a direction] 297 lks”
About five-seven
Google Earth allows Smoots for the ruler tool. But they spell it out in full. I was hoping they would allow it for general measurements, which would force them to use an abbreviation, but they only allow imperial and metric for that. 
As far as I can tell, there is no abbreviation or shorthand for Smoot. I used to run across the Harvard Bridge several times a week, every 364.4 smoots ± 1 εar.
for those of you who are ignorant, here is the Straightdope’s official list of conversion factors, for various types of measurements:
copied from this wonderful thread, two decades ago
Since Smoot ended up in the Bureau of Standards, you would think if there was a symbol, he would have created it.
Smoot was a 5’7" Harvard student and some fellow students decided to measure the length of the Harvard bridge (between Cambridge and Boston) in Smoots.
Shouldn’t the plural be smeet?
Smooten.
MIT, not Harvard. The bridge across the Charles River in front of MIT is called the Harvard Bridge, named after John Harvard, not the college.
Wasn’t that list taken from the official rules for 43-man Squamish?
What about the shit-ton and its metric equivalent?
How many other Directors or Presidents of the Bureau of Standards have had units of measurement named for them?
this guy wasn’t a director of an agency, just an engineer. But he did invent my favorite unit of measurement. His last name was Gilbreth, so he invented the “therblig”, for motion analysis.
Therblig - Wikipedia.
I think that every physics teacher in history has named either the unit of momentum or the unit of electric field after themself.
The name doesn’t usually stick.
