8 / 2 (2 + 2) =

Some hospitals will weigh you in kilograms.
And going back to the original (sarcastic) comment, your weight on the moon will be six times less than on earth, but your mass will stay the same.
 
Nothing wrong with expressing material quantities in units of mass, in fact it's probably technically more accurate since it doesn't change with gravity. As long as you understand the difference between weight and mass.

I was going through a 172R manual, and in the weight and balance section, they give tables in both English and SI units. In the SI unit flight envelope table, the moment is given in kilogram meters. If one of my engineers ever gave me a calculation in kilogram meters, they would be fired on the spot.

As shown it’s really unclear. Without brackets around the 2(2+2) it is 16. Assuming brackets it’s 1. I’ve seen this many times as an engineer where someone implies a math operation but does the math wrong anyway.

Exactly. It doesn't have brackets or parathesis around 2(2+2). If it did have brackets it's a different question. In my opinion you cannot assume they meant to put brackets around 2(2+2). If you want the answer to be 1 the equation would be 8/(2(2+2)), but that is not what is written.

But since we’re arguing about technically correct stuff, “six times less than,” say, 200 pounds would be a negative 1000 pounds. Did you mean “one sixth the weight on earth”? :devil:
