Either I’m missing something (quite possible), or Google‘s calculator converts between joules and calories incorrectly.
According to pretty much everyone else (e.g. here), a calorie is 4.184 kilojoules. According to Google’s calculator, it’s 0.004184 kilojoules.

Heh, I noticed this about a year ago and tried emailing/sending a comment to Google about it, but obviously it went unnoticed. I’m glad it’s not just me who notices these things 🙂

I was missing something 🙂 I noticed kcal on a packet of food today, so I actually looked it up. Turns out there are “small” and “large” calories, and really what lay-people call calories are kilo-calories, so Google is really right.
Seems to me they should have a “did you mean kilocalories?” addition to the searches, since this is the common use…

That’s very likely wrong. I was using it to check some homework, and it came up with this:
diameter of the earth = 1 275 620 000 centimeters
It’s wrong! They added an extra zero, I checked my calculations many times.

If you do sin(45) or cos(22) it gets them all wrong. It is rubbish.
