According to the debate, they had their reasons. But still – when one hundred and eighty six nations say one thing, and two say another, you have to wonder about the two.

There’s 470 joules of energy in a 9mm. That’s 0.1 kcal, i.e. you need approx. 666 mp5 mag dumps for your daily energy expenditure.

The bullet energy is from several sources and it’s below 500 joules. 2,000 kcal is 8,400,000 joules.

Another way to approximate this: there’s about 0.3g of gunpowder in a 9mm cartridge. There’s about 3 kJ/g of energy in gunpowder, i.e. one 9mm has about 1 kJ worth of gunpowder. So with the gunpowder alone you’d need almost 10,000 rounds for your daily energy needs.

Welcome to /c/tumblr, a place for all your tumblr screenshots and news.

Our Rules:

  1. Keep it civil. We’re all people here. Be respectful to one another.

  2. No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.

  3. Must be tumblr related. This one is kind of a given.

  4. Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.

  5. No unnecessary negativity. Just because you don’t like a thing doesn’t mean that you need to spend the entire comment section complaining about said thing. Just downvote and move on.
