• 1

  This page converts Therms to Kilowatt-hours using the exact reference factor 29.307222. That is the standard figure, so the results here match reference tables rather than rounded approximations.

• 2

  With very large or very small Therms values, read the full Kilowatt-hours result before copying it — scientific notation is easier to misjudge than a plain number, especially across several orders of magnitude in one conversion.

• 3

  Enter plain decimal numbers without thousand separators: a comma can be read as a decimal mark in some locales and silently change the magnitude of the Therms value you meant to convert to Kilowatt-hours.

• The exact factor for Therms → Kilowatt-hours carries 8 significant digits (29.307222); rounding it early to 29.3 drifts a 1,000 therms input by about 7.2222222 kilowatt-hours. Round only the final displayed answer.

• Decimal separators corrupt input silently: a comma can be read as a thousands separator and shift a Therms value by ×1000. Control check: enter 2.5 and confirm the result equals 73.268056 Kilowatt-hours before trusting larger values.
