"For those using non-metric, Alternate units seem to work as ft for length, force, kips, Area (ft^2). Or, use # instead of kips: Depend on E, G, etc. ;) As long as you are consistant with the units throughout, it should all add up. Also, increase of…"

"When we are using meter for length, E is in Pa or GPa? For example E for Steel= 200 GPa, if A=0.2 m2 and L=1 m, K= (200 x 10^9 x 0.2) / 1  Does it make sense?!!!"

"Thanks! That's brilliant, thanks Daniel, really appreciate it, time to dig out my old tables of moduli!  As a more general side note, Kangaroo is ace, cheers for that also! All the best! Rup"

"Not so! - See above. I've just never gotten around to writing them up until now"

"Let's see, it's just a question of being consistent... You can take your Rhino dimensions in metres, your mass is in Kg, and your force in Newtons Then for your axial spring stiffness use EA/L  where E is Young's modulus in Pa A…"

### Units (mass & force)

Hi all, I'm pretty new to Kangaroo and I'm trying to work out how various objects and structures respond to differnernt forces, mainly unary force for gravity and some spring stuff within the structures. I was wondering if there is a unit kangaroo uses for mass and for force (g and N?)  or a conversion ratio of some kind?  Or am I fundamentally misunderstanding how these work in Kangaroo?  (I've searched the forums...etc, and just can't seem to find an answer.) Many thanks for your help and…See More
