thickness mm  
weight g  


lb/cu ft 

example: a 3" sheet of 3/32" balsa weighs 15g
when measured it is 76mm wide, 915mm long and 2.4mm thick
entering those values into the claculator and clicking on 'calculate' we get 5.61 lb/cuft

light or soft is anything between 4 and 5.5 lb/cuft
medium goes from 5.5 to 6.5 lb/cuft
heavy or hard ranges from 6.5 to 9.5 lb/cuft though some is more dense still

spruce is around 28 lb/cuft
