Apple’s Weird Math, or the Weight of the iPad

I was looking at the specs for the new iPad Air 2, comparing its weight with last year’s original iPad Air. I’m unimpressed by the difference in thickness between the devices, but wanted to see how much difference the thinner iPad meant in terms of weight. On Apple’s page where you can compare iPad models, I saw this:


(I’ve edited the above, so the images display right about the weight section, which is quite far down on the Compare iPads page.)

I you think for a second, you realize there’s something wrong with the math. The iPad Air 2 weighs 32 grams less than the original iPad Air; that’s almost an ounce, or 1/16 of a pound. But the difference between the two – .96 lbs and 1 lb – is clearly wrong. Last year’s iPad Air actually weighs 1.03 pounds, yet Apple rounds this down to a pound. For other models, they have un-rounded numbers: .98 lbs for the Wi-Fi + Cellular model of the iPad Air 2, 1.05 lbs for last year’s version. But last years Wi-Fi iPad Air is curiously an even pound.

I suspect that Apple rounded down last year, and, since they did so, they can’t change the weight, but a simple calculation shows their error. It’s odd; you’d think they’re want to better highlight the difference between the two models: 32 grams, or just over 1/16 of a pound, or, to be precise, 0.07 lbs. When you compare the two in the above graphic, if you aren’t familiar with the conversion (454 g = 1 lb – you’d think there’s less of a difference in weight.

This isn’t a big deal, but it’s a spec that’s clearly wrong (at least in pounds).

What do you think?
