WHAT IS THE U.S.A measure for Mass.?

Question

Hello you now how eurpoe uses Celcius and we use ferrenheight they use kilos we use pounds, what is the USA measure for Mass.

Answer 1

Here's where things get complicated!

Sometimes the pound is used either as a unit of weight (or force) and sometimes it's used as a unit of mass.

Most commonly when people refer to pounds, they are talking about weight. In that case, the corresponding unit of mass is the 'slug'. A slug is the amount of mass that accelerates by 1 ft/s^2 when a pound of force is put on it... that makes it 32.17405 pounds (in 1 Gee) or 14.59390 kg.

Sometimes people use pounds to refer to mass instead. In that case, the unit of force becomes the 'poundal'. A poundal is one pound-foot-per-second-squared, or exactly 0.138 254 954 376 newtons.

But, as people mentioned above, nobody in their right minds uses either of those units, even Americans. Most American scientists just switch to the metric system when they actually want to discuss such things. Hope that helps!

Answer 2

The USA doesn't really have a seperate unit of mass, but we use pounds to mean mass. Also scientists use mass.

It is only the everday American people that cling on to all those silly old scales that make arithmetic such a nightmare.
