what is the formula for converting pounds to kg?

Question

Help- please and thank you.
Also... what is the mass of the Earth?

Answer 1

1 lb = 0.454 kg.
1 kg = 2.2 lbs.

Either of these formulas will work for converting lbs to kilograms:
amount in kilograms = amount in pounds / 0.454
amount in kilograms = 2.2 * amount in pounds

The mass of the Earth is:
5.9742 × 10^24 kilograms (about 6 octillion kilograms)
or
1.31708565 × 10^25 lbs (about 13 octillion pounds)

Answer 3

Conversion Pounds To Kg

Answer 4

1 kilogram = 2.20 pounds (I kg = 2.2 lbs )
1 pound = 0.45 kg

1 pound is 454 grams. Tha's 0.454 kilograms. 1/.454=2.2026. 1 kilogram is 2.2026 pounds.

Earth is the 3rd planet from the Sun at a distance of about 150 million kilometers (93.2 million miles). It takes 365.256 days for the Earth to travel around the Sun and 23.9345 hours for the Earth rotate a complete revolution. It has a diameter of 12,756 kilometers (7,973 miles), only a few hundred kilometers larger than that of Venus. Our atmosphere is composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other constituents.


The planet Earth is only a tiny part of the universe, but it is the home of human beings and all known life in it. Animals, plants and other organisms live almost everywhere on Earth's surface. It ranks fifth in size, and its mass is found to be about 5.98 × 1024 kg. Mass is a characteristic that is inherent, and it is independent of the object's environment and the method used to measure it. It is a scalar quantity, that is, a single value with and appropriate unit that has no direction.

The mass of the Earth may be determined using Newton's law of gravitation. It is given as the force (F), which is equal to the Gravitational constant multiplied by the mass of the planet and the mass of the object, divided by the square of the radius of the planet. We set this equal to the fundamental equation, force (F) equals mass (m) multiplied by acceleration (a). We know that the acceleration due to gravity is equal to 9.8 m/s2, the Gravitational constant (G) is 6.673 × 10-11 Nm2/kg2, the radius of the Earth is 6.37 × 106 m, and mass cancels out. When we rearrange the equation and plug all the numbers in, we find that the mass of the Earth is 5.96 × 1024 kg.

F = Gm1m2/r2 = ma

Gm/r2 = g

m = gr2/G

m = (9.8 m/s2)(6.37 × 106 m)2/(6.673 × 10-11 Nm2/kg2)

m = 5.96 × 1024 kg

The Earth gains mass each day, as a result of incoming debris from space. This occurs in the forms of "falling stars", or meteors, on a dark night. The actual amount of added material depends on each study, though it is estimated that 10 to the 8th power kilograms of in-falling matter accumulates every day. The seemingly large amount, however, is insignificant to the Earth's total mass. The Earth adds an estimated one quadrillionth of one percent to its weight each day.

Answer 6

lbs./2.2= kg (the amount in pounds divided by 2.2 gives you the amount in kilograms)

The mass of the Earth is about 6.0 x 10^24 kg, which is also equal to approximately 6,000,000,000,000,000,000,000,000 kg.

Answer 7

2.2 pounds = 1 kg

Answer 8

1 kg=2.2 lb
so, pounds to kg = (pounds/2.2 lb) kg
I hope this helps.
mass=density/volume

Answer 9

1kg=2.2lb

Answer 10

1Kg=2.2lbs
