Is the weight 1 pounds or 1.034 pounds?

The page reads:
Weight: 1 pound (469 g)

1 pound ~ 453.59
469g ~ 1.034 pounds

So which is it?

My guess, 469 grams is the more accurate figure, and when they converted to pounds, they rounded it off to 1 pound. After all, as another poster pointed out, 0.034 pounds seem hardly significant.

It should be 1.034 I think. If you look at the other iPads, there's always 0.02-0.03lb difference between WiFi and WiFi+Cellular version.

Apple just wants to make the figure nice by rounding it at 1.0lb.

Is the 0.034 pound extra a deal breaker?

Not a dealbreaker, but there is too big a difference to round off.

I would say removing 3.2% weight while rounding is significant. What is the reason they write the cellular as 1.05 lbs and not round it off to 1 lbs too or write both as 1.05? The difference between 1.034 and 1.05 is smaller than that between 1.034 and 1.

So you think they should market the iPad Air as weighing 1.01 Pound?

It's not even 0.1 more, not even close to half of that.

It's not even close half of 0.01!

Apple are well within their right to say the iPad Air weighs 1 Pound.

No, no its not.

In third grade maths we our taught rounding.
4 and lower round down, 5 and higher round up.

1.03 has a 3, which is smaller than a 4, so its entirely expected to round down to 1.0.

No, they should market it to weigh 1.034 or at least 1.03 pounds, which is what the weight is. Or 1.05 if they want to round their iPads to the closest multiple of 0.05 lbs as they have done with the cellular.

No, no its not.

In third grade maths we our taught rounding.
4 and lower round down, 5 and higher round up.

1.03 has a 3, which is smaller than a 4, so its entirely expected to round down to 1.0.

It all depends on which scale of rounding we are aiming for. If we are rounding to the closest full pound the cellular should be rounded to 1 lbs too. What Apple seems to have done if we also look at the cellular version is that they are rounding to the closest multiple of 0.05 lbs, which means that both the WiFi and cellular should be rounded to 1.05. If you are going to be a smart ass about it you should get your third grade rounding correct.

Thank god you don't work in Apple's marketing department :)

What is wrong with using the same standard of rounding on all their versions to get as accurate measurements as possible? As a consumer I don't care if it looks bad from a marketing position, when I buy a product I want to know the actual weight, not some made up weight that looks better from a marketing standpoint.

Well, they seem to be rounding at two digits beyond the decimal point, so in that sense you are right that they should have rounded to 1.03. But I guess it was so close to 1 pound, they just decided to call it a pound. Personally I don't mind, and I wouldn't mind if the cellular model was also marketed as being a pound, but I guess they have to show the weight of the cellular radio somehow.

I mean, how is .03 or even .05 of a pound going to affect how we use an iPad?

You are still confused. Lets try again.

For the wifi model they are rounding to the nearest tenths, thats the digit right after the decimal. The number lower than that is a 3, so they round down to zero.", and present 1.0 lb.

For the cellular version, they are rounding 1.053 lb to the nearest hundredths. Again we have a 3 behind it, giving 1.05 lb.

I have another tidbit that might hurt your mind, be warned yiu may want to skip the next part.

For BOTH variants, they rounded to the nearest ones place for measurement in grams. Giving us 469 and 478 g that were rounded up or down from something!

The average consumer would not care in the slightest bit if a product weighs 0.034 lbs more or less than it actually does. You know absolutely nothing about advertising and marketing.

As I already typed. Rounding like that and choosing different bases for your rounding when comparing 2 products is sketchy at best and not best practice. This means from a mathematical standpoint that the comparison between the WiFi and cellular version become quite meaningless since you have no idea what rounding have been used by just looking at the weights in lbs.

In the case of the grams they most likely used the same standard for both, that is they rounded them both off to the closest integer. Which is standard practice.

When it's an issue of weight of devices, the lower the better. I disagree with any rounding down in cases of weight when a lower weight is more desirable. Sound like false advertising to me, and an ill-considered mis-representation by Apple.

They should have gone with 'Slightly over a pound'.

Don't say I'm been overly-critical. As someone before pointed out, it's a 3.2% difference in weight, which is rather significant in my opinion.

Not meaningless. It shows that the cellular weighs more by an amount so insignificant that I'd need a scale to tell the difference.

If you're trying to calculate the fuel needed to get a Saturn rocket to break orbit and into space and adding up all the hundredths and thousandths of pounds from every part. It might make a difference.

But if that were you, you'd weigh it yourself and not trust a consumer marketing spec.

You found the more accurate weight on the Apple website.

For those who care about the EXACT weight, the information is there for them, on the Apple website.

For the rest who don't really care, 1 Pound is definitely close enough :)

=)) This is the first time I see someone really seriously care about the weight.
Why don't you just wait to try it in the store. When you find it comfortable in your hand then all the weight/thinness are meaningless.

For me who live in Europe anyhow I don't see the weight in pounds in my store anyhow. I just got surprised when I saw the weight in my countries Apple Store since it differed from the 1 pound that was shown during the presentation yesterday.

Maybe I am just showing the actuary in me but I think it's annoying when marketing people use math in a questionable way to enhance some positive aspects of their product. And yes, my wife who work in marketing in the tech field sometimes gets mad at me too for being too exact :p.

What a stupid thread.

It's the best that the shills could come up with.

There's SO MUCH wrong with this tablet, like… .03lb weight deception and… it doesn't come with a keyboard… oh, and it is called "AIR"… like, what a scam!
