Conversions entre \(\pu{m/s}\) et \(\pu{km/h}\)

◉\(\begin{aligned}[t] \pu{1 m*s-1} &= \dfrac{\pu{1 m}}{\pu{1 s}} \\ &= \dfrac{\pu{10^-3 km}}{\pu{\frac{1}{3600} s}} \\ &= (\pu{{10^{-3} × 3600}) km*h-1} \\ &= \pu{3,6 km*h-1} \end{aligned}\)

◉ \(\begin{aligned}[t] \pu{1 km*h-1} &= \dfrac{\pu{1 km}}{\pu{1 h}} \\ &= \dfrac{\pu{10^3 m}}{\pu{3600 s}} \\ &= \pu{\dfrac{1}{\pu{3,6}} m*s-1} \end{aligned}\)

Conversions entre \(\pu{mol*L-1}\) et \(\pu{mol*m-3}\)

◉ \(\begin{aligned}[t] \pu{1 mol*L-1} &= \dfrac{\pu{1 mol}}{\pu{1 L}} \\ &= \dfrac{\pu{1 mol}}{\pu{10^-3 m^3}} \\ &= \pu{10^3 mol*m-3} \end{aligned}\)

◉ \(\begin{aligned}[t] \pu{1 mol*m-3} &= \dfrac{\pu{1 mol}}{\pu{1 m3}} \\ &= \dfrac{\pu{1 mol}}{\pu{10^3 m3}} \\ &= \pu{10^-3 mol*L-1} \end{aligned}\)

Conversions entre \(\pu{s*m-1}\) et \(\pu{mS*cm-1}\)

◉ \(\begin{aligned}[t] \pu{1 S*m-1} &= \dfrac{\pu{1 S}}{\pu{1 m}} \\ &= \dfrac{\pu{10^3 mS}}{\pu{10^2 cm}} \\ &= \pu{10 mS*cm-1} \end{aligned}\)

◉ \(\begin{aligned}[t] \pu{1 mS*cm-1} &= \dfrac{\pu{1 mS}}{\pu{1 cm}} \\ &= \dfrac{\pu{10^-3 S}}{\pu{10^-2 m}} \\ &= \pu{10^-1 S*m-1} \end{aligned}\)
