Convert your lists to quantities before using UnitConvert Edep = {4.9491200000000017`*^-14 Joules, 1.8669264000000004`*^-14 Joules, 6.223088000000001`*^-15 Joules}; mass = {0.043937500000000004` g, 0.06987` g, 0.02329` g}; dose = UnitConvert[Quantity[Edep/Joules, "Joules"]/ Quantity[mass/g, "Gram"], "Joules/kg"] {Quantity[ 1.1264000000000004*^-9, "Joules"/"Kilograms"], Quantity[ 2.6720000000000007*^-10, "Joules"/"Kilograms"], Quantity[2.672*^-10, "Joules"/"Kilograms"]} This can be shortened dose = UnitConvert[Quantity[Edep/Joules, "J"]/ Quantity[mass/g, "g"], "J/kg"] {Quantity[ 1.1264000000000004*^-9, "Joules"/"Kilograms"], Quantity[ 2.6720000000000007*^-10, "Joules"/"Kilograms"], Quantity[2.672*^-10, "Joules"/"Kilograms"]} % == %% True Bob Hanlon On Thu, Nov 7, 2013 at 12:28 AM, mariusz sapinski < mariusz.sapinski at gmail.com> wrote: > I have the following lists: > Edep = {4.9491200000000017`*^-14 Joules, > 1.8669264000000004`*^-14 Joules, 6.223088000000001`*^-15 Joules} > mass = {0.043937500000000004` g, 0.06987` g, 0.02329` g} > > I want to calculate dose: > dose = Edep/mass > > I get another list (of Quantities): > > {(1.1264*10^-12 Joules)/g, (2.672*10^-13 Joules)/g, ( > 2.672*10^-13 Joules)/g} > > OK, but I want to have Grays, ie.
