The best unit of measurement to determine the mass of a book is grams.
Weigh? mass in kilograms or pounds.
The metric (SI) unit for weight is the newton, since weight is a force. When people talk about "weight", they sometimes actually mean "mass". The unit for mass is the kilogram.
grams most oranges weigh between 200 and 800 grams
Mass is measured in grams.
Gram.
Weigh? mass in kilograms or pounds.
gram is the unit for mass, out of your choices.

Technically, you can measue a book in any unit of weight or mass. However, the most correct answer for your question would be kilograms. Kilograms are closer to a bound where as miligrams are closer to 1/10th of a oz
The gram already is a unit of mass.
Considering that grams are a unit of mass, their mass would still be 100g. If you used a unit of weight, such as pounds, the relative weight of an object would change from planet to planet. On Mercury, a person who weighed 100 lbs normally would instead weigh 38 lbs.
milliNewtons. A gram or kilogram is a measure of mass, not weight.
Units of weight or mass for a book would be in pounds and ounces or grams and kilograms.
The yard is a unit of length, not a unit for mass !!
Nothing can 'weigh' two grams, because the gram is not a unit of weight (it is the metric unit of mass). However, two grams would likely weigh something close to the weight of a pencil.
The SI unit of weight is the Newton. Strictly speaking g and Kg are units of mass. 1 kg of mass is the same mass everywhere. It would weigh much less on the moon than on the earth. The same with a ballpoint pen. ballpoint pen would weigh about 0.5N
Horsepower is not a unit of mass.
