Lankeela://"Just divide both by 30" - how would anyone know that?"// - err because there are 30 centimetres in a foot, do you have a ruler? Have a look at it!
You always seem angry on these threads lankeela, why is that? We are just trying to help, yes I know you are not interested in knowledge, I suppose I just hope that a small amount might inspire you to want more.
lanks: Take no notice of TCL he's just nitpicking as usual. there are just over 30cm in a foot, 30cm is generally accepted as close approximation of a foot, when he himself points out at 12:01. I guess the urge to nitpick overrides all other processes.
