Is it true that Muscle weights more than Fat?

I'm not fat, I'm stout! :embarassed: :glasses:

But what if I only have a kg of muscle??? Then what?? Oh yeah!

Then I need to know where you're measuring. A pound of muscle in Salt Lake City weighs the same as a pound of fat at the top of Mount Everest, but you can't say the same for a kg. ;-)

Right! because a kg is a measure of mass.

A mass of muscle in Salt Lake City weighs slightly less on top of Mount Everest, because of the tiny difference in gravity caused by moving further from the center of the earth.

But that's just nit-picking, I know.

isn't a pound a measure of mass too? I thought they were similar measures? (Metric girl here, I don't know about pounds...)

Aha, apparently a pound used to be weight, but it was later linked to the kilogram so now it does measure mass. Since 1 July 1959, the international avoirdupois pound has been defined as exactly 0.45359237 kg. It's on wikipedia.

I did not know that. So if someone asks me "How much would I weigh on the surface of Mars", what units should I use?
