What Does W/(g2 cm3) Represent in Power Density Units?

[joshmorris]

Homework Statement

So I saw a unit "W/(g2 cm3)"
And I'm pretty sure it's about power density...and I understand what W/cm3 is. It's watts per cubic centimeter...but what does the g mean? grams? If so, how does that fit in? :/[/B]

 

[Student100]

Sure it wasn't $(W/g^2)/cm^3$?

W/(g2 cm3) is the exact form

 

[Bystander]

Can you give us any context?

 

[Student100]

W/(g2 cm3) is the exact form

That's okay, it's technically the same thing. I've only ever seen it written in this form in relation to power densities:

$(mW/g^2)/cm^3)$

Normally in reference to maximum power densities.

Yes, what is the context you saw it in?

There are other places where I saw mW instead of W, what does it mean though?

-It is regarding maximum power densities

Milliwatt

 

[joshmorris]

Milliwatt.

Not mW I knew that, I meant the rest of it...like could you say it framed like "x cubic centimeters" or like full meaning in practical terms...
Like what does the g mean D:

I saw a unit "W/(g2 cm3)

Where? In what reference? In what context?

Without that sort of information we can't answer your question.

Also, is this homework? If so, you should be filling out the complete homework template, including an actual problem. What you've given isn't a problem, it's just a question.

Here's a paper that references it,

http://iopscience.iop.org/article/1...sessionid=D6364882AAD5BE845D65B93DAC700020.c1

Figure 4. Has units $(W/g^2)/cm^3$

It almost always has something to do with vibration energy harvesting, I don't know that much about it. Just remember seeing it once before.

I figured it out, acceleration.
