Can any one explain the what does 'E' denotes in Mass. Attached pic.

Hello mozkhan, your units are grams and millimetres so :E+04 = 10000 , E+07 = 10000000Mass 8.508E+04 g means : 8.508 x 10000 = 85'080 g = 85.08 tonsVolume 1.084E+07 mm^3 means : 1.084 x 10000000 = 10'840'000 mm^3 = 0.010'84 m^3I don't know if Fusion 360 is like AutoCAD but if you display less zero after the comma in your units you will get direct numbers like : 1000 and not 1E+03.

OK mozkhan :Volume 1.084E+07 mm^3 = 10'840'000 mm^3 # 0.01084 m^3 x 8000 kg/m^3 = 86.72 kgIs that OK ?

Yes. Thanks for explaining in detail.
