Question

who many dyne r there in 1 Nm with full derivation​

Answer 1

1 newton meter (N-m)

= 10,000,000.00dyne centimeters (dyn cm)

One dyne is equal to 10 µN (micronewtons), or to 10 nsn (nanosthenes) in the old meter-tonne-second system of units. Equivalently, the dyne is defined as "the force required to accelerate a mass of one gram at a rate of one centimeter per second squared": 1 dyn = 1 g. cm/s2 = 10^−5 kg
