Question

Name some non-SI units of force ?

Answer 1

Answer:

Non-SI units of force are ➡️

▪︎DYNE 》

The CGS unit of force is dyne. One dyne is that much force which produces an acceleration of 1cm/s² in a body of mass 1 gram.

▪︎Gram Force》

It is the gravitational unit of force in the CGS system it is denoted as gram force(gf).

One

▪︎Kilogram Force 》

It is the gravitational unit of force in the metric system and it is denoted by kgf.gram force is that much force which produces an acceleration of 9.81m/s² in a body of mass 1kg.

Answer 2

Some non-SI units of force are:

pound force (lbf)

dyne (dyn)

gram force (gf)

kilogram force (kgf)

• The pound-force is defined a bit different than the Newton. pound-force is a foot-pound-second unit of force, equal to the force that produces an acceleration equal to the acceleration of gravity when acting on a mass of one pound.

1 Newton ≈ 0.22481 pound force

pound force 1 pound force ≈ 4.44822162 newtons

• dyne is a unit of force that, acting on a mass of one gram, increases its velocity by one centimetre per second every second along the direction that it acts. It is the CGS unit of force.

1 dyne = 1.0 × 10-5 newtons

• The gram-force is a metric unit of force (gf). The gram-force is equal to a mass of one gram multiplied by the standard acceleration due to gravity on Earth, which is defined as exactly 9.80665 meter per second. It is the gravitational unit of force in the CGS system .

1 gram force gf = 0.0098 newtons

• The kilogram-force is also called kilopond. The value of the kilogram-force is defined in terms of the standard terrestrial force of gravity. Kilogram-force is a non-standard unit and is classified in the International System of Units (SI) as a unit that is unacceptable for use with SI. It is the gravitational unit of force in the metric system.Both the pound-force and the kilogram-force are units which depend upon the force of terrestrial gravitation.

1 kilogram force = 9.80665 newtons

Extra information :

The SI unit of force is the kilogram-metre per second squared which is called the newton (1 N = 1 kg-m/s2).

About newton

1. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in the direction of the applied force.
2. The newton is obtained as a result of Newton's first law of motion, force equals mass times acceleration; one newton is that force which when applied to a mass of one kilogram imparts to it an acceleration of one metre/second2.
3. Conversion factors between the other units of force and the newton are: 1 dyne = 1.0 x 10-5 N (exactly); 1 kilogram-force = 9.80665 N (exactly).
4. The relation between the actual force of gravity and mass is given by Newton's law of gravitation, F = gmm'/l2, where m and m' are the masses of the two attracting objects, l is the linear distance separating them, and g is the Newtonian constant of gravitation. The value of g is found to be 6.67259(85) x 10-11 m3 kg-1 s-2.

(if calculated per 9.81 N)

then

Kg to Newton 1 kg = 9.81 N

Newton to kg 1N = 0.10197 kg
