What unit is molecular weight measured in?

Answer 1

In the current and internationally accepted SI system, the basic unit of mass is the kilogram. The unit of force,

a derived quanity, is the newton. One newton is the force with which one body pulls another body (of mass 1kg) towards itself with a acleration of 1 meter per seconds squared.

In the English system, the basic unit of mass is called a pound, or more

properly pound-mass, since a pound is also the derived unit of weight. A pound

of force is the amount required to accelerate 1 pound of mass (called a slug)

at the rate of 32 feet per second per second.

Answer 2

Weight is force. Any unit of force is an appropriate unit with which

to describe weight. Some of the more popular ones include . . .

-- Newton

-- Pound

-- Ounce

-- Ton

-- Stone

-- Dyne

Note:

During your survey, two answers that will score high in your results are "kilogram"

and "gram". Those are not units of force, and you must discard them. I strongly disagree with the last answer shown here. There are 2types of 'Unit'. There are 'Fundamental ' units, and there are 'Derived' units . There are also 2 systems of units . There is the Metric system , and the British system. In the metric system there are actually 2 fundamental systems, there is the cgs system, and the mks system. The fundamental units are the units of Mass, Length, and Time. cgs stands for centimetre, gram, second . mks stands for metre, kilogram, second. The fundamental units for scientific work, are based on the metre kilogram second. Mass and weight and force, have, and use, the same units. (but they are defined differently). It is quite legitimate to measure weight in any multiple or any fraction of the fundamental unit. Therefore weight can be measured in kilogram, gram, tonne. The units named the dyne, and the newton are reserved for applications where we measure force, or pressure, or surface tension. In the British system the fundamental units of Mass, Length, and Time, are the foot, the pound and the second. It is named, the fps system. The fundamental unit of weight is the Pound. It is quite legitimate to measure weight in any multiple of, or fraction of, the pound. Therefore weight in the British system can be measured in pound, or ounce, or ton. Derived Units are units which use (usually) more than 1 fundamental unit to define them. Examples are:- Density - gram/ cm cubed. Pressure - Newton/ Metre squared. Volume is a derived unit which uses only 1 fundamental unit, but it uses it in a different way. It measures 3 lengths, and gives them a new name (derived from length). It names it as Volume. The Newton and the Dyne are both units of force which are DERIVED from the fundamental mass unit, called the gram (CGS) and the kilogram (mks). Other examples of derived units are, Velocity, Acceleration, Power, Momentum, stress. There is a strict nomenclature to follow when using scientific or engineering units. The use of 'upper or lower case' letters must be followed to avoid confusion. Example : A kiloPascal unit of pressure is abbreviated to :- kPa not KPa .

Answer 3

Molecular weight is measured in Atomic Mass units (u) or grams per mole (g/mol).

Answer 4

usually weight is measured in pounds (lb)
