Conversion 8.10^7 t -> Gt 14.10^-7 g -> microgramme 620.10^6 W -> kW 0.68kg.m^-3 -> g.cm^-3

8.10^7 t = 0,08 Gt

14.10^(-7) = 1,4 micro g

620.10^6 W = 620.10^3 kW

0,68 kg/m^3 = 0,68*1000 / 10^6 = 0,68.10^-3 g/cm^3

Bonjour,

8×10⁷ t=0.08×10⁹ t=0.08 Gt

14×10⁻⁷g=1.4×10⁻⁶g=1.4 μg

620×10⁶W=620000×10³W=620×10³ kW

0.68 kg.m⁻³=680 g.m⁻³=680×10⁻⁶ g.cm⁻³=6.8×10⁻⁴g.cm⁻³
