Detailed explanation-1: -Glossary: Mass (weight) Units. The Metric System of Measurements uses the mass units: gram (g), kilogram (kg) and tonne (t).
Detailed explanation-2: -The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 x 10–34 when expressed in the unit J s, which is equal to kg m2 s–1, where the metre and the second are defined in terms of c and Cs.
Detailed explanation-3: -The kilogram (abbreviation, kg) is the Standard International (SI) System of Units unit of mass. It is defined as the mass of a particular international prototype made of platinum-iridium and kept at the International Bureau of Weights and Measures.
Detailed explanation-4: -1 kg = 1000 g. So, to convert grams (the smaller unit) to kilograms (the larger unit), we divide the quantity in grams by 1000. How can we depict 100 grams in kilograms? Since 1 kg = 1000 g, we can say 100g = 0.1 kg.
Detailed explanation-5: -The gram (originally gramme; SI unit symbol g) is a unit of mass in the International System of Units (SI) equal to one one thousandth of a kilogram. The mass of this pen cap is about 1 gram.
