Welcome to /c/tumblr, a place for all your tumblr screenshots and news.
Our Rules:
-
Keep it civil. We're all people here. Be respectful to one another.
-
No sexism, racism, homophobia, transphobia or any other flavor of bigotry. I should not need to explain this one.
-
Must be tumblr related. This one is kind of a given.
-
Try not to repost anything posted within the past month. Beyond that, go for it. Not everyone is on every site all the time.
-
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.
Sister Communities:

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.
This math does not feel correct. Are you sure you are not confusing a kilocalorie of energy with a thousand NUTRITIONAL calories, which is iirc a thousand times less energetic?
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.
