Solution
Dear Benedict,
Dyne is the CGS unit of force.
1 Newton=1 kg m s-2=105 g cm s-2 = 105 dyne
1 gram weight = 0.001 kg weight = 0.001×9.8 = 9.8×10-3 N
Now let us convert Newton into dyne.
9.8×10-3 N=9.8×10-3×105=9.8×102=980 dyne
Therefore, 1 gram weight = 980 dyne
Dyne is the CGS unit of force.
