Strange.............

All the reference books I read refer to weight in grams or kilograms. I don't own a single cookery book that says use 'x' newtons of minced beef for this recipe.

Similarly, when I get weighed by the doctor he never says I weigh 'X' Newtons, it is always in kilograms.

Once again, when I go to the market and ask for a bag of apples the seller doesn't put them on the scales and say they weigh 'x' newtons.

When I take my dog to the vets and they put him on the scales I don't get told he weighs 'x' newtons.

I vaguely remember doing this mass thing at school but in real life we don't use the term mass and use the term weight instead. Have you ever seen a metric/imperial chart that actually states Newtons on it?!? I haven't, although I would like to see one. So, if anyone can provide a link to one I would be most interested.

Technically CWanamaker is correct, weight is a force and measured in Newtons. However we tend to use mass and weight interchangeably in common speech. In physics / applied mechanics though, weight and mass have specific meanings. Mass is the amount of "stuff" in an object and weight is the force exerted by the gravity of the planet measured in Newtons. The weight of an object would be less on the Moon for instance than the same object on Earth.
The SI (Systeme international d'unite) specifies the unit of mass as the kilogram not the gram and this is used for all engineering and scientific calculations.
This is the SI website.

There are only 7 basic units. All other units are derived and given a special name. For instance the Newton is the name given to the quantity Kgm/ (sec)2

You guys are all wrong. The gram and kilogram is a measure of mass NOT Weight. Weight is a force that incorporates the acceleration of gravity into it. In the SI system, the unit of weight is the Newton. It is a derived unit (as opposed to a base unit) with base notation written as kg-m/s^2. Basically, you could convert any mass value to a weight value by multiplying by the acceleration of gravity.

For example, a person with a mass of 100kg has a weight of 981 Newtons (or 0.981 kN)

The most commonly used measurements in increasing order of weight: nanogram (1/1,000,000,000 of a gram), microgram (1/1,000,000 of a gram), milligram (1/1000 of a gram), gram, kilogram (1000 grams), and metric ton (1,000 kilograms).

As a frame of reference one pound is approximately 454 grams.

The gram is the metric unit of weight. It makes no difference whether is a gram, a microgram or kilogram as they are all multiples of the same thing.

The metric unit of weight is the kilogram, not the gram, and is equal to 1000 grams

The metric unit of weight is the Gramme (Gram)
1000 grams = 1 Kilogram
