Kilowatt-hours to British thermal units

1 kilowatt-hour = 3,412.1 British thermal units · 1 BTU = 0.00029307 kWh

1 kilowatt-hour = 3,412.1 British thermal units

How it’s calculated

BTU = kWh × 3412.141633

  • Multiply the value in kilowatt-hours by 3412.141633.
  • To go back, divide by 3412.141633 (or multiply by 0.0002930710702).
  • 1 kWh = 3,412.141633 BTU · 1 BTU = 0.0002930710702 kWh
Show worked solutionFactor, unit cancellation and rounding, step by step

  1. Find the conversion factor

    By definition 1 kWh = 3600000 J and 1 BTU = 1055.05585262 J, so 1 kWh = 3412.14163312794 BTU. Source: NIST SP 811 / Handbook 44.

  2. Multiply by the factor written as a fraction

    Put kWh in the denominator so it cancels, leaving BTU.

  3. Calculate (unrounded)

  4. Round the answer

    Rounded to 5 significant figures.

Answer: 3412.1 BTU
