1 Hartree (Eh) = 27.21138602 eV = 4.359744650×10−18 J
= 627.509474 kcal/mol = 2625.499638 kJ/mol
= 219474.6313702 cm−1 = 6579.683920711 THz
= 315775.13 K

Atomic Length Converter

Relationship used: 1 Bohr = 5.2917721067×10−11 m [2]

Temperature Converter

K (Kelvins):
°C (Celsius):
°F (Fahrenheits):
°R (Rankines):









K = °C + 273.15 = (°F + 459.67) * (5/9) = °R * (5/9)
°C = K - 273.15 = (°F-32)(5/9) = (°R - 491.67) * (5/9)
°F = K * (9/5) - 459.67 = (9/5)°C + 32 = °R - 459.67
°R = K * (9/5) = (°C + 273.15) * (9/5) = °F + 459.67
