text: 1danm=?nm or 1danm= ?kgm? torque conversion table the use of "da" is for "deka" or "deca" meaning ten (10), so 1 danm = 10 nm. it was very common to use dan in engineering works as a dan is very close to a kg of force (in earth at least). 1 danm = 0.980665 kgm. just remember that this kg are force or weight, not mass.
