Can radius of gyration be used to non-dimensionalise the equation of motion for a thin beam?

Due to stretching effect, the coefficient of the non-linear term (arising due to the stretching effect) is getting very large. In some paper radius of gyration is used to nondimensionalise the...

Are there multiple measurement units of muscle/tendon stiffness ?

I have seen in the literature that stiffness is sometimes represented in kPA (kilopascals), N/m (Newton per meter) and KN/m (kilonewton per meter). Do they represent the same?
