*Below is a quote from a scientific paper about measurements of energy in an average lighting strike. My question: What's* MJ/m? Stan
"The energy released by lightning is measured in megajoules, also expressed as MJ/m." “For example a single megajoule is equivalent to about 200 food calories, or the energy from leaving a microwave on for 20 minutes to cook food,” he explains. “It can also be compared to a 60 watt lightbulb’s energy use if left on for about four hours. It’s also the same as the kinetic energy a car has traveling about 60 mph.” Their research found that the energy produced by a lightning strike peaked at greater than 20MJ/m.
