Unit Conversion Table

This table is practical to convert between different common units. To convert from a unit $Y$ in the left hand column to a unit $X$ in the top row, mutiply by the table element, $M_{X,Y}$.

For example, to convert from hartree to eV you do

1 hartree = 27.2107 eV.

	hartree	eV	$\mathbf{cm^{-1}}$	kcal/mol	kJ/mol	J
hartree	$1$	$27.2107$	$219 474.63$	$627.503$	$2 625.5$	$43.60 \cdot 10^{-19}$
eV	$0.0367502$	$1$	$8 065.73$	$23.060 9$	$96.486 9$	$1.602 10 \cdot 10^{-19}$
$\mathbf{cm^{-1}}$	$4.556 33 \cdot 10^{-6}$	$1.23981 \cdot 10^{-4}$	$1$	$0.002 859 11$	$0.011 962 7$	$1.986 30 \cdot 10^{-23}$
kcal/mol	$0.001 593 62$	$0.0433634$	$349.757$	$1$	$4.18400$	$6.95 \cdot 10^{-21}$
kJ/mol	$0.000 380 88$	$0.01036410$	$83.593$	$0.239001$	$1$	$1.66 \cdot 10^{-21}$
J	$2.294 \cdot 10^{17}$	$6.24181 \cdot 10^{18}$	$5.034 45 \cdot 10^{22}$	$1.44 \cdot 10^{20}$	$6.02 \cdot 10^{20}$	$1$
