What is the basic SI unit used for measuring mass?

Answer 1

The newton is the SI basic unit of force.

While there is no SI basic unit for weight, we use the kilogram and pound as the operational or practical units of weight. This is the effect that an object has on the calibrated springs of a scale.

However, this answer is useful only in very basic math classes and in commerce.

The correct answer is that the basic unit of MASS is the kilogram and the basic unit of FORCE is the newton.

If we use weight to mean mass, it is wrong because mass is a scalar quantity. We can use weight to mean force, but force is a vector quantity and measured in newtons.

In aerodynamics, weight is used only as a vector quantity to describe the 4 forces that affect an object interacting with a fluid medium: Weight, drag, lift and thrust.

Answer 2

Weight is nothing but mass under the influence of acceleration due to gravity (g)

According to Newton's Second Law, F = m x a

Therefore , Weight = mass x (acceleration due to gravity)

SI unit is N or kg m/s2

SI unit of mass = kilogram (amount of matter something contains)

Si unit of force (weight) = newton (mass * acceleration due to gravity)

>

Force (Weight) of 1 kg mass on earths surface.

Using force = mass * acceleration

Force = 1 (kg) * 9.82 (metres per second - per second)

Force = 9.82 newtons

>

What you see on the kitchen scales is kilograms force, equal to kilograms mass as long as your at the earths surface radius.

Multiply * 9.82 to get newtons
Since weight is a force, it is measured in newtons.

Please be sure you don't confuse weight with mass. Mass is measured in kilograms. If you are not sure about the difference, check the Wikipedia article on "Mass versus weight".

Answer 3

Weight is a measurement of the gravitational force between two objects (usually the Earth is one of them). Because of this, the Newton, the SI unit for force, is also the unit for weight.

Answer 4

The basic SI unit used for measuring mass is the kilogram (kg).

Answer 5

We measure this force in SI units called Newtons (N). One newton = 0.225 lbs
the newton

Answer 6

There is no base unit for weight in SI. The unit for weight is the newton, which is a derived unit.

Answer 7

Weight exists due to some gravitational force so the SI unit is newton (N)

Answer 8

Weight is force. The SI unit of force is the Newton.

Answer 9

The Newton, N, is the Si unit for weight and is equivalent to the mass in kg over acceleration in m/s^2 due to gravity. N = kg.m/s^2

Answer 10

The SI unit for weight is the newton.
