Conversion Formula
MWh = µJ × 2.777777778e-16
About Microjoules
A microjoule (µJ) is 10⁻⁶ J - the scale of precision laser ablation, ESD damage events, and individual LIDAR pulses. LASIK eye surgery delivers 0.5-2 µJ per pulse at 193 nm, ablating ~0.25 µm of corneal tissue per pulse. ESD events that destroy IC gates correspond to 1-1,000 µJ; the Human Body Model test discharges ~500 µJ at 2 kV. Q-switched microchip laser pulses for rangefinding are 1-100 µJ. The kinetic energy of a 1 mg grain of sand falling 10 cm is mgh ≈ 0.98 µJ. 1 µJ = 10⁻⁶ J.
About Megawatt-Hours
A megawatt-hour (MWh) is the energy from 1 MW for one hour - exactly 3.6 GJ. It is the standard unit for wholesale electricity trading. Power purchase agreements (PPAs) specify capacity and price in $/MWh or €/MWh. A 5 MW wind turbine at full capacity generates 5 MWh/h. Primary aluminium smelting consumes 13-15 MWh per tonne. The Moss Landing battery (California) stores 3,287 MWh. The daily output of a 1 GW nuclear plant at 90% capacity factor is ~21,600 MWh. 1 MWh = 3.6 GJ = 3,412,141 BTU = 1,000 kWh.
