I think you're confused, mass and weight are related .. here on Earth we use the term weight to signify the 'lift-ability' of an object .. that is it 'weighs' one kilogram (2.2lbs)
in space where weightlessness is accepted .. it would show as no weight in your arms or on a set of scales .. however if it was moving it would still have the effect of one kilogram of force on you .. so although you could lift a tonne of weight in space, if you were hit by it, the result would be the same as a one tonne object hitting you on Earth - because it has Mass - i.e. at rest it has no visible 'weight' but to move it requires at least one kilo plus of force to move its' mass

Weight is equal to mass times the acceleration of gravity.
W = mg, with W being weight in newtons, m being mass in kilograms, and g being the acceleration of gravity in m per second squared.
The weight of one kilogram would be 1 kg x 9.8 m/s^2 = 9.8 newtons.

Weight is a force and force is mass times acceleration (Newton's Second Law). The easy answer is 2.2 pounds, but that is the English System (pounds are force units). To get the weight in the Metric System multiply the mass by the acceleration of gravity (9.81 m/sec^2).
1 kg * 9.81 m/sec^2 = 9.81 newtons.

At sea level, a kg of mass weighs one kg.
Below sea level it would weigh slightly more.
Above sea level it would weigh slightly less.
Gravity varies with altitude.

1000grams, dependng on which pole of the earth you are, it can be up to 1100 grams or lighter than 1000 grams in some places
