Convert Millijoules to Watt-hours

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

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

Going the other way? Convert Wh to mJ.
