One pound of weight on Earth is equal to 454 grams, and 1,000 grams equal 1 kilogram. Thus, a kilogram on Earth is about 2.2 pounds, so 400 kilos = 880 lbs. Note that a kilogram measures the amount of matter in an object, and pounds measure the amount of gravitational force on an object. So one kilogram on a planet smaller than Earth, (IE, Mercury,) would weigh far less than 1 lb, and a kilogram would weigh much more on a larger planet, like Jupiter.
As a cavity, the mouth has no true weight, though the jaw/skull and tissue would have some weight. But to separate that from the weight of the skull itself would be difficult if not impossible!
About 1 pound
No, brick is not a mineral. Minerals are naturally occurring inorganic substances with a specific chemical composition and ordered atomic structure, whereas brick is a man-made building material typically composed of clay or other materials that are heated and hardened.
bruise. Just like a ring can cause stinging pain, a brick can cause bruising when it hits someone.
1 kilogram
By a kg I believe you mean 1 kilo... which would be the answer.
No, the volume of a 2-kilogram iron brick would not be twice that of a 1-kilogram iron brick. The weight of an object does not directly correlate with its volume, as volume is determined by the dimensions and density of the object, not just its weight.
2 kg (1b=1kg+1/2b, 1/2b=1kg, 1b=2kg)
No, the inertia of an object is directly proportional to its mass. In this case, a 2 kilogram iron brick has twice the mass of a 1 kilogram iron brick, so it also has twice the inertia.
Weight of 1 Kg Brick = 9.8 Newtons
A kilogram is a unit of weight.
1 kilogram is the mass of about 441dimes.
The weight of a 1-kg brick is 9.81 Newtons, which is the force exerted on the brick due to gravity.
1 kilogram = 15,432.36 grains.
1 kilogram of water weighs one 1 kilogram or 2.20462262 pounds
The weight of one liter of water is approximately 1 kilogram.
