Write the relationship between-(i) kgf and newton(ii) gf and dyne

(i) The relationship between kilogram-force (kgf) and Newton (N) is as follows:

1 kgf = 9.80665 N

The kilogram-force (kgf) is a unit of force commonly used in countries like India, where the force exerted by the weight of a kilogram mass is taken as the unit. On the other hand, the Newton (N) is the International System of Units (SI) unit of force, defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

(ii) The relationship between gram-force (gf) and dyne (dyn) is as follows:

1 gf = 980.665 dyn

The gram-force (gf) is a unit of force commonly used in some engineering and technical contexts, particularly in relation to small forces. It is defined as the force exerted by the weight of a gram mass under standard gravity (9.80665 m/s²). The dyne (dyn) is the CGS unit of force and is defined as the force required to accelerate a one-gram mass by one centimeter per second squared.
