No they don't. A kilogram is a kilogram, whether on the Earth at the North Pole or on the bright side of the moon. Same for a meter, same for a liter.
Actually the moon's gravity is 1/6 that of Earth so a kilogram on Earth would be 1/6 kilogram on the moon.
Also technically gravity is slightly stronger at the north pole so a kilogram at the equator would be slightly more than a kilogram at the north pole.
You're confusing lbs with KG, kg's don't change as a result of gravity.
Data is completely different. Data is simply a count. Like, I have 3 apples. All of our measuring devices are subject to physical variations such as temperatures, pressures etc. The units are also defined by substances, for instance, 1 KG is 1 L of water. 1 L doesn't change based on external forces, but the amount of water contained within that space sure does hence the definition of 1 KG being 1 L / water needs contraints on the variables that affect it.
Data is simply a count. I transfered 3 apples, either you did or you didn't, there are no external forces that change that count. it's either right or it's wrong
Pounds and grams both measure the same thing: mass. 5 kg = 11.023 lbs on Earth as well as the moon.
Nope. Grams and their variants are a measure of the amount of mass an object has. Pounds is a measure of the force of gravity over an object. An object will weigh less on the moon, but will still have the same mass. Does no one take science class these days?

there is a mass pound, but the general term lb/pound refers to a weight, which is a force not a mass. Because the mass pound and the force pound (weight) are so closely labeled, Grams are much preferred for use of mass.

lbs are imperial units for mass, kilograms are [SI] units for mass.
