The weight of an object is mass multiplied by gravity. The basic weight unit is the gram (g), using the The Metric System of Measurements of mass. In modern scientific usage, weight and mass are fundamentally different quantities: mass is an intrinsic property of matter, whereas weight is a force that results from the action of gravity on matter: it measures how strongly the force of gravity pulls on that matter and this force is measured in Newtons. However, in most practical everyday situations the word "weight" is used when, strictly, "mass" is meant. For example, most people would say that an object "weighs one kilogram", even though the kilogram is a unit of mass.
Here are multiples of the mass:
1 microgram (µg) = 1000 nanograms
1 milligram (mg) = 1000 micrograms
1 centigram (cg) = 10 milligram
1 decigram (dg) = 10 centigrams
1 gram (g) = 10 decigrams
1 decagram (dag) = 10 grams
1 hectogram (hg) = 10 decagram
1 kilogram (kg) = 10 hectogram
1 megagram (Mg) / ton (t) = 1000 kilogram |
