WebHow to convert Megawatt Hour to Gigawatt Hour (MWh to GWh)? 1 MWh = 0.001 GWh. 1 x 0.001 GWh = 0.001 Gigawatt Hour. Always check the results; rounding errors may occur. In relation to the base unit of [energy] => (joules), 1 Megawatt Hour (MWh) is equal to 3600000000 joules, while 1 Gigawatt Hour (GWh) = 3600000000000 joules. WebSo the initial energy is going to be equal to 100 joules. That's cause this is 0 and this is 100. So the initial energy is 100 joules. At this point right here, what's the potential energy? Well we're 5 meters up, so mass times gravity times height. Mass is 1, times gravity, 10 meters per second squared. Times height, times 5. So it's 50 joules.
