Electricity & Grid Audit Calibrator (kWh ↔ MJ)

Analyze electric billing kilowatt-hours and physical energy auditing megajoule metrics.

kWh
MJ
💡 A kilowatt-hour represents the energy consumed by a constant power load of 1,000 watts running for exactly one hour. It simplifies electrical resource bills. 1 kWh stores exactly 3,600,000 Joules (or 3.6 MJ).
