Convert Watt-hours to Millijoules

Watt-hours → Millijoules
Wh × 3600000 = mJ mJ × 0.0000002777778 = Wh

To convert watt-hours (Wh) to millijoules (mJ), multiply the watt-hours value by 3600000. 1 Wh = 3600000 mJ, and 1 mJ = 0.0000002777778 Wh. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert mJ to Wh.
