Ha in kWh Umrechner - Hartree in Kilowattstunde

Conversion derivation

Express both Ha and kWh 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 kWh in the base unit

   $$1\mathrm{kWh}=3,600,000\mathrm{J}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{Ha}& =\frac{4.35974472\times 10^{-18}\cancel{\mathrm{J}}}{3,600,000\cancel{\mathrm{J}}}\times 1\mathrm{kWh}\\ & =\frac{4.35974472\times 10^{-18}}{3,600,000}\mathrm{kWh}\\ & =1.2110402\times 10^{-24}\mathrm{kWh}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{kWh}& =\frac{3,600,000\cancel{\mathrm{J}}}{4.35974472\times 10^{-18}\cancel{\mathrm{J}}}\times 1\mathrm{Ha}\\ & =\frac{3,600,000}{4.35974472\times 10^{-18}}\mathrm{Ha}\\ & =8.2573642\times 10^{23}\mathrm{Ha}\end{array}$$
