How tall is everyone?

OK, let's see, everyone added together? Like, standing on shoulders?
If the average man is 1.7m and the average woman 1.6m, the average person is 1.65m
With 6 billion adults, this gives us 9,900,000,000m

Children are tougher, but let's try. 2 billion of them, and newborns average 0.5m. So, averaging between adult height and 0.5m gives us 1.075m. Multiplying this by 2 billion gives us 2,150,000,000m

Adding together, we get 12,050,000,000m.
And that's how tall everyone is. Ish.

Unless they're just standing next to each other. In which case, a little bit less.

I'm tired, it's probably full of errors, it doesn't matter :D
Is there a BOOOOOOOOO emoji?
 
The half is important!
Well, we might use the halves even with centimeters. And even a whole centimeter is less than half an inch.

I once ordered a made-to-measure clothing item from a company that's handled from US and thus using inches, though the factory is in India and very much using metric system. How inaccurate to give just whole inches! 0,5cm ≈ 1/5 inch would be a more appropriate unit for made to measure.
