Assuming the book is on Earth where acceleration due to gravity is 9.81ms-2;
F=mg
F= 2.1 x 9.81 = 20.6N
Therefore, the weight of a book of mass 2.1Kg on Earth is 20.6N
10 stone 9 pounds = 21 kilograms
It is equal to 47.18 pounds approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply kg by 2.204 to get the equivalent pounds.
21 pounds = 9.525 kilograms.
It is 46.297 lbs (approx.). Kilogram is the SI unit of mass and pound is an imperial unit of mass. To convert from kg to pound, multiply the kg unit by 2.20462.

10 stone 9 pounds = 21 kilograms
There are 6.35029318 kilograms in one stone. Therefore to get amount of stones in kilograms, value in kilograms has to be divided by amount of kilograms in one stone: 21 kilograms = [kilograms] / 6.35029318 = 21 / 6.35029318 = 3.3069 stones
21 pounds = 9.525 kilograms.
It is equal to 47.18 pounds approximately. Kilogram is the metric unit and pound is the imperial unit for mass. 1 Kilogram is 2.204 pounds. So we multiply kg by 2.204 to get the equivalent pounds.
