You know what annoys me? (well, one of the things anyways...)
When something gives/asks for weight in grams/kilograms. That's not weight!!!
Pounds are weight. Ounces are weight. Newtons are weight.
Grams (kilo- etc) are NOT weight. They are mass!
Pounds:Newtons as Slugs:Kilograms.
Yes, in case you didn't know, the imperial (AKA, the effed up system the USA uses) unit for mass is a "slug"... which is weird. Even more weird, the "small" version of that is the "slinch" (slug-inch) also called a "blob"... I mean, come on! Are we trying to get all the other countries to laugh at us?!?!
Mass times acceleration (almost always gravity) is what gives weight. Thus, you have a different weight on the moon. However, if you "massed" yourself, it would be the same.
*Sigh* Now that I've taken general physics, mistakes like this annoy me... also, I'm yet to go through a day without thinking about a physics equation!
