The biggest I’ve seen in a published source in the wild is an 80-fold error in a reported distance, which I think came from a series of at least three unit conversions and area/length misinterpretations.

Always bothers me that I can’t trust 90% of people (myself included) to properly state area, square feet or feet squared, very different scales.
Square feet are feet squared.
3 square feet are 3 1x1 feet, 1/3rd of a square yard. 3 feet squared is a square yard, 3x larger than 3 sqft.
Unless I’m missing your sarcasm.
Also the purpose of this xkcd
Edit to add, a 600 square foot studio apartment (about 3% of an acre) is much smaller than the 600 foot squared lot that a mcmansion will sit on. (About 9 acres)
I believe “feet squared” and “feet, squared” is the discrepancy here.
The unit ft^2 is pronounced “feet squared” and is equivalent to sq. ft.
"the Louisiana purchase added 838,000 square miles to the United States, tell me, was it 1/4 the size of the United States, or the 100x the surface area of the sun?
One of those are square miles, the other is miles squared.
But I don’t know why I expect you to understand this now.
No need to add the comma if you say it properly, feet squared are not squared feet, quantifier (3) adjective (square) noun (feet) vs quantifier (3) noun (square) affective (feet), it’s the order of operations in the English language, one is quantifying the distance of the edge, while the other is quantifying how many individual edges (squares) of set distance (feet) you have.
I am not writing it with any discrepancy, though I do get tripped up when talking about it, but generally nobody calls anyone on it, except that’s when expensive projects go boom sometimes.
Read out loud 3sqft and 3’^2,
First one: 3 square feet
Second one: 3 feet (foot? If you’re pedantic) squared (square if you’re a pedant)
Read out loud “three squared” and 3^2
Did you not notice the unit modifier in the my second phrase???
Let me spell it out for you.
3 (three) ’ (feet) ^2 (squared)
You’d have me repeating myself like a monkey, which is, NINE.
3 (three) sq (square) ft (feet) is THREE.
but I suspect you’ll disagree at at this point I’ll move on, my only sadness is there was a person out there who agreed with your original argument that they were the same.
Tell me what “three plus four squared” is.
