It's an old cheat question, world often confused mass and also density and assume steel is the exactly answer.

You are watching: What weighs more a kilogram of feathers

Strictly speaking, a kilogram is not an unit of "heaviness", but of mass. Depending on your meaning of "heavy", a kilogram that steel can be heavier. That's because a kilogram of feathers is larger, and thus much more buyoant in the neighboring air.

For example, if the 2 sit on a communication at sea level in the atmosphere, the stole kg exerts a greater pressure on the platform, or "feels heavier" for the platform.

For an instance that much better shows the impacts of buyoancy: a kilogram that helium balloons vs a kilogram the steel.

That certain question is false. HOWEVER, there room comparisons where there IS a difference, which makes it a party concern rather 보다 a cheat question.

Which is heavier, a pound of feather or a pound of gold?

The feathers. Precious steels are weighed utilizing Troy ounces, and also there's just 12 of lock in a (Troy) pound.

Which is heavier, an ounce of feathers or an ounce of gold?

The gold! A trojan ounce is slightly bigger than one avdp. Ounce.

Have fun through your new knowledge!!

That's the dumbest thing I've read in a while. The concern was "An ounce of feather or an oz of gold".

At no point was it claimed "An ounce of feathers and also a troy ounce of gold".

That's like saying "What's heavier, an oz of feathers or an oz of gold" and also the answer gift "The feathers! Feathers room measured in tons, therefore an ton-ounce of feather is heavier".

A trojan ounce of feathers is the same as a troy ounce of gold BTW, so the prize is the same.

Precious metals are weighed using Troy ounces

Except, ya know, once they're not, prefer in the paper definition of this question. A scale doesn't sense as soon as you put precious metals on it and also convert indigenous the normal standard.

I'd tell you it's choose saying the a dozen doughnuts is an ext than a dozen eggs since a baker's dozen is actually 13, but I'm concerned you'd agree with me, rather than get the point.

They are wrong

Seriously depends on the context.

In a physics great "steel is heavier" will be correct because of several reasons.

Let's to speak the concern is "you've obtained steel v the fixed of one kg and also fathers with the exact same mass and put lock on a scale here on earth. I beg your pardon one weighs more?".

Now come someone through grade school expertise if physics it's apparent that it's a trick question, however to physicists it's apparent that buoyancy and also gravity both have actually an effect. (feathers need an ext space, for this reason the center of massive is more away from the facility of mass of earth compared to the facility of massive of steel)

tl;dr: it's a trick concern unless you research physics
