# what is relation between the newton and dyne ?

Asked by Shruti Mishra(MAHARISHI PATANJALI VIDYA MANDIR) , on 22/12/13

Dyne is CGS (centimeter-gram-second) form of Newton (which is SI unit form). Please do cross check this information.

1 Newton = 1000 dyne

Just think of it this was, 1 Kilogram = 1000 gram, makes sense now right?

1 newton = 1 kg m/s2

and 1 dyne = 1 g cm/s2

Now, 1 Kg=1000 g and also 1 m = 100 cm.

So, 1 newton = 1000 g 100 cm/s2

1 newton = 105 g cm / s2

1 newton = 105 dyne.

Whoops, I meant 100,000 dyne. My bad.

both are the unit to measure force but the difference is that newton is SI unit and dyne is C.G.S. unit.

relation between newton and dyne

we know, 1 newton = 1 kg m/s ...... (1)

now 1 kg = 1000g = 103g

1 m = 100 cm = 102cm

put these values in eqn.(1), we get

therefore 1 newton = 103gX 102cm /s2

= 105g cm/s2

but 1 g cm/s2= 1 dyne

therefore1 newton = 10 5 dyne

Let

F = 1N

m = 1kg

a = 1 ms-2

We know,

F = ma

Substituing the values in the eqnwe get

1N = 1kg x 1 ms-2

since 1kg = 1000g , 1m = 100 cm

1N = 1000 g x 100 cm-2

1N = 105 g cms-2

since 1 dyn = 1 g cm-2

1 N = 105dyn
