[latex]1,3 h = 1,3cdot3600s = 4680 s\\2,7 kN = 2,7cdot1000N = 2700 N\\290 mg = 290cdot0,001g = 0,29 g\\420 N = 420cdot0,001kN = 0,42 kN\\55 dm^{3} = 55cdot0,001m^{3} = 0,055 dm^{3}\\8,5 cm^{3} = 8,5cdot0,001dm^{3}} = 0,0085 dm^{3}\\56frac{kg}m^{3}} = 56cdotfrac{1000g}{1000000cm^{3}}=0,056frac{g}{cm^{3}}\\52frac{kg}{m^{3}} = 52cdotfrac{1000g}{1000dm^{3}} = 52frac{g}{dm^{3}}[/latex]
