soil concentration units

1 cm 3 = 1 ml (milli litre) 1 dm 3 = 1 litre 1000 dm 3 or 1000 litre = 1 m 3 1000 ml or 1000 cm 3 = 1 dm 3 or 1 litre y % = ( y x 10 000) ppm y ppm = ( y / 10 000) % Y % = Y g/100g Y ppt ( parts per thousand) = Y g/kg or Y g/1000g Y % = ( Y x 10 ) ppt Y ppt = ( Y / 10) % Y ppm = Y mg/kg Y ppm = Y ug/g = Y microgram/gram Y ppm = Y ug/ml Y ppm = Y mg/litre Y ppm = ( 2 x Y ) ibs/acre ( pounds/acre ) Y ppm = Y g / 1000 kg Y ppm = Y g/metric tonnes Y kg/ha = ( Y / 1 000 ) metric tonnes /ha Y ibs/acre = ( Y / 2 ) ppm Y ibs/acre = ( 1.12 x Y) kg/ha Y kg/ha = ( Y / 1.12 ) ibs/acre. Molality = moles of solute / kg of solution. Equivalent weight (mg/meq) = ( molar mass / valency ) ( this is a guess formular, not very precise but simple to understand.) Gram equivalent weight = mass in gram / equivalent weight Milli equivalent weight = mass in mg / equival...
