Can I convert cal/cm2 to ohms/cm2?

[bobbi]

first, I am not electrically savy, I will end up contracting an engineer to do the arc flash calculations my facility needs to do.

Just so I have some idea of the amount of energy they are talking about is there a way to convert cal/cm2 to ohms/cm2?
This is in reference to PPE for qualified persons working on energized equipment.


I am not a math whiz either, so please keep it simple.

Thanks for any resources or direction

No, they are not realated at all. Calories is a measure of heat energy.

You can convert cal/cm2 to joules/cm2. These are both energy.

Yep, 1 cal = 4.1868 Joules

Not sure why you would want to convert to ohms/cm2, that would not be an energy measurement...

Anyway, just to give you an idea, 1.2 cal/cm2 is roughly the amount of energy necessary to get a second degree burn. If you're in an adventurous mood, try this: (kids, don't do this at home)

Light a butane lighter and hold your hand about one inch above the blue part of the flame for one second. When you remove your hand, you should have a second degree burn, and a good idea of how much energy 1.2 cal/cm2 is.

Now multiply that several times, over most of your body, and you've got an idea of what 40 cal/cm2 is...
