What does 1 millijoule equal in kilowatt-hours?

1 millijoule equals approximately 2.7777777777778e-10 kilowatt-hours.

Why convert millijoules to kilowatt-hours?

To relate very small-scale energy measurements to larger energy units used in electrical billing and energy analysis.

Is this conversion practical for everyday energy billing?

No, because millijoule measures very small amounts of energy and kilowatt-hours are used for much larger energy scales.
