In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. Nevertheless, one...

In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance...

weight rating for its weight carrying capacity. Curb weight (American English) or kerb weight (British English) is the total mass of a vehicle with standard...

In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is...

Human body weight is a person's mass or weight. Strictly speaking, body weight is the measurement of weight without items located on the person. Practically...

Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat (adipose...

Power-to-weight ratio (PWR, also called specific power, or power-to-mass ratio) is a calculation commonly applied to engines and mobile power sources...

In boxing, a weight class is a measurement weight range for boxers. The lower limit of a weight class is equal to the upper weight limit of the class...
