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.
