Ha a kJ convertitore - Hartree a Kilojoule

Conversion derivation

Express both Ha and kJ in the same base unit J (joule), then cancel the shared base unit.

1. 1

   Rewrite Ha in the base unit

   $$1\mathrm{Ha}=4.35974472\times 10^{-18}\mathrm{J}$$
2. 2

   Rewrite kJ in the base unit

   $$1\mathrm{kJ}=1,000\mathrm{J}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{Ha}& =\frac{4.35974472\times 10^{-18}\cancel{\mathrm{J}}}{1,000\cancel{\mathrm{J}}}\times 1\mathrm{kJ}\\ & =\frac{4.35974472\times 10^{-18}}{1,000}\mathrm{kJ}\\ & =4.35974472\times 10^{-21}\mathrm{kJ}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{kJ}& =\frac{1,000\cancel{\mathrm{J}}}{4.35974472\times 10^{-18}\cancel{\mathrm{J}}}\times 1\mathrm{Ha}\\ & =\frac{1,000}{4.35974472\times 10^{-18}}\mathrm{Ha}\\ & =2.29371228\times 10^{20}\mathrm{Ha}\end{array}$$
