You are watching: **what is heavier a kilogram of feathers or steel** In **buntips.com**

Their **masses are identical**. The only thing that will be different is their volume. Even if you compressed the feathers until you squeezed all the air out, they would still be seven times the volume of the iron.

Originally Answered: What is heavier, 1kg of feathers or 1kg of steel? **1kg of steel is slightly heavier than 1 kg of feathers**. 1 kg of feather will displace more air as the density of feather is very less comparitively. More the volume displaced more is the upthrust and less the apparent weight.

The mass of 1 kg of feathers and **1 kg ok bricks are identical**. And if you want an answer to your question comparing the weight on Earth of those 2 items, in vacuum of one kilogram of feathers would have exactly the same weight as one kilogram of bricks.

Question: – “How come a pound of steel and **a pound of feathers weigh the same**?” Because that’s the definition of weight, which is the attraction of a mass to another their mass. If the attraction if the two masses is the same, the weight is the same. This is because they both weigh a pound.

**0.0082 grams** Ornithologists commonly measure birds’ feathers as a proportion of total body weight. A 5-pound broiler chicken’s feathers weigh about 74 grams or 2.6 ounces, or 3.3 percent of its body weight. Since that chicken has some 9,000 feathers, each one weighs about 0.0082 grams.

**Iron** being a metal element, and cork being what it is, Iron is much more dense then cork, even if the you have the same weight amount. So the amount/volume you would need to have a Kg of cork would be greater then the amount to make a Kg of iron. Hope it helps.

They would both be equal in weight. The difference wil be in the density. You would need a lot more feathers to make up a ton than you would need bricks, because **bricks are more dense than feathers**. As a result, a ton of feathers will be larger in size, and the bricks will take up less space.

## Why is iron heavier than cork?

A pound of rocks or a pound of **feathers both weigh the same**. However, the density of rocks is more than that of the feathers so the rocks have a lesser volume than an equal mass of feathers.

A ton is a ton, of course; but **bricks have much greater density than feathers**, and so we are tempted to think of them as heavier. … A ton of feathers and a ton of bricks have the same mass, but the feathers make a much bigger pile because they have a much lower density.

An avoirdupois ounce converts to 28.34 grams approximately. The troy ounce is 31.1 approximately. … In the Troy system only 12 ounces equal a pound. So a pound of feathers weighs **453.59 grams approximately** and a pound of gold weighs 373.24 approximately.

But if we try to lift a ton of iron or a ton of feather in air, we’ll feel that **iron is more heavier than feather**. This is because of the lift air provides for feather bundle due to it’s higher volume. More the volume, more lift by air and easier to lift. In this case, one ton iron will be heavier to lift in air.

They both weigh the same. A POUND of feathers vs. a POUND of rocks. A pound is a pound, and whether it is a pound of feathers or a pound of rocks, it doesn’t matter.

0082 grams. This means you’d need about **121,951 feathers**. So you could try to picture 121,951 feathers and stop there but if you’d like further visual aid the average chicken has 9,000 feathers this means to get a kilogram of feathers you’d have to pluck 13 and a half chickens.

“Which weighs more–a pound of lead or a pound of feathers?” The seemingly naive answer to the familiar riddle is **the pound of lead**. The correct answer, of course, is that they weigh the same amount. We investigated whether the naive answer to the riddle might have a basis in perception.

So this question is kinda tricky, But the answer is that they weigh the same. Because it is already mentioned that a feather weighs 1 pound and so **a brick also** weighs 1 pound. So, their weigh should be equal but there might be more feathers in 1 pound.

1. Pound is an imperial unit of mass or weight measure while kilogram is a metric unit of measurement. … One kilogram is approximately equal to 2.2 pounds. So **a kilo is 2.2 times heavier than a pound**.

However, iron is “denser” than cork **because the mass of an iron atom is greater than the mass of an atom of cork (carbon)**. Also, iron is more compact than the cork, so its density is much higher than cork.
## Which is more dense a kilogram of iron or a kilogram of wood?

## How many feathers does it take to make a pound?

## What falls faster a ton of bricks or feathers?

## Which is heavier a pound of stones or a pound of cotton?

## Which has more mass rock or feather?

## Which is heavier a ton of iron or a ton of feather?

## How heavy is a brick?

However, **any piece of iron is denser than any piece of wood**, and is less dense than any piece of lead. If an object is made of multiple materials, its average density is the total mass divided by the total volume. … This definition means that 1 liter (equal to 1000 cm3) of water has a mass of 1 kilogram.

There is about **275-300 feathers** in a pound.

Galileo discovered that **objects that are more dense, or have more mass**, fall at a faster rate than less dense objects, due to this air resistance. A feather and brick dropped together. Air resistance causes the feather to fall more slowly.

Technically, **a pound of stones has more mass**, it has more matter than a pound of cotton balls.

A **pound of rocks** on earth (not in a vacuum) is slightly heavier than a pound of feathers; this is because ‘rocks’ obviously have a higher density than ‘feathers’, assuming the feathers are loosely held and not tightly packed. Neither is heavier ’cause they all have the same weight.

A ton of feather is **much more heavier than a ton** of metal because a ton of feather has more surface area and volume thus occupies great space due to which it experiences high upthrust ( force exerted by air) as comparable to a ton of metal and is much more heavier despite having same mass.

You can expect an average brick weight to be **about 5 pounds (2.27 kg)** for a standard red clay brick. The standard size measures to be 8-inch by 2 1/4-inch by 4-inch.
## Which is heavier an ounce of gold or an ounce of feathers?

## Why is 16 oz in a pound?

**An ounce of gold**, like in this 1-ounce gold American Eagle, weighs more than an ounce of feathers. Gold is measured in troy ounces (each equal to 31.1 grams); feathers are measured in avoirdupois ounces (28.35 grams each).

The avoirdupois weight system’s general attributes were originally developed for the international wool trade in the Late Middle Ages, when trade was in recovery. It was historically based on a **physical standardized pound** or “prototype weight” that could be divided into 16 ounces.
## How heavy is lead vs gold?

Whether it is heavier would depend on the relative quantities. “Heaviness” is not a measurable quantity. The Atomic Weight of **lead is greater than that of gold (207 versus 196)**, but the Density of gold is much greater than that of lead (19.32 versus 11.34 g/cc).

## Limmys Show: Whats heavier a kilogram of steel or a kilogram of feathers

## A kilogram of steel IS heavier than a kilogram of feathers. Here’s why.

## What weighs more ??? A ton of Bricks or a ton of Feathers ???

## Kilogram of Steel or Kilogram of Feathers, Asking my Sister reaction

The weight of an object is given by the product of its mass and acceleration due to gravity on the surface. In this case, both feather and stone have **same mass**. … So, the weight of both 1 kg of feather and 1 kg of stone will be same. Hence, both will weigh same.

First, a kilogram is a unit of mass, so **1kg of feathers has the same mass as 1 kg of steel**, and both have the same weight in the same gravitational field. However, if you put a block of steel with a mass of 1kg on a scale, then do the same for the feathers, the steel will weigh more than the feathers.

But how much does a feather weigh? On average, a feather weighs just **0.000289 ounces (0.0082 grams)**. That’s really light! Ornithologists frequently study birds and their feathers.

Precious metals like gold and silver are measured using the “troy” system where there are 12 ounces in a pound. If you normalize everything to mass a pound of feathers is 454 grams and a pound of gold is 373 grams, therefore **the feathers are technically heavier**.

Feathers are made from keratin, with a density of about **1.3 g/cm3**. The net volume displaced by a kilogram of feathers is then 751 cm3. Steel has a density of 7.86 g/cm3 and a kilogram of it displaces 127 cm3.
