Ha から Wh 変換ツール - ハートリー から ワット時

Conversion derivation

Express both Ha and Wh 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 Wh in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{Ha}& =\frac{4.35974472\times 10^{-18}\cancel{\mathrm{J}}}{3,600\cancel{\mathrm{J}}}\times 1\mathrm{Wh}\\ & =\frac{4.35974472\times 10^{-18}}{3,600}\mathrm{Wh}\\ & =1.2110402\times 10^{-21}\mathrm{Wh}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{Wh}& =\frac{3,600\cancel{\mathrm{J}}}{4.35974472\times 10^{-18}\cancel{\mathrm{J}}}\times 1\mathrm{Ha}\\ & =\frac{3,600}{4.35974472\times 10^{-18}}\mathrm{Ha}\\ & =8.2573642\times 10^{20}\mathrm{Ha}\end{array}$$
