Hartree to British thermal unit converter (eh to btu)

Conversion Formula

1 eh = 4.13e-21 btu

Step-by-Step Explanation

1. Understand the base relationship:
   1 Hartree = 4.36e-18 joules
   1 British Thermal Unit = 1.06k joules
2. Establish the conversion factor:
   1 eh = (4.36e-18 J) / (1.06k J/btu) = 4.13e-21 btu
3. Apply the conversion:
   Multiply the value in eh by 4.13e-21 to get the equivalent in btu

Example Conversion

Convert 5 eh to btu:

5 eh × 4.13e-21 = 2.07e-20 btu
