Zamień jednostkę z g/cm^3 na kg/m^3 [latex]  frac {g}{cm^{3} } [/latex] = ?

1 kg = 10³ g 1 g = 10⁻³ kg 1 m³ = 100 cm*100 cm *100 cm = 10⁶ cm³ 1 cm³ = 10⁻⁶ m³ 1 g/cm³ = 10⁻³ kg / 10⁻⁶ m³= 10³ kg/m³

7·[latex] frac{1/1000}{(1/100) ^{3} } [/latex]=7·[latex] frac{1/1000}{1/1000000} [/latex]=7·[latex] frac{1}{1000}[/latex]·1000000 = 7·1000=7000 kg/m³
