Cubic Unit Factor Label Conversions (g/cm3 to kg/m3)

In this video I’m gonna take you through a Cubic Unit Factor Label Unit Conversions So this is, uh, AP Level, College Level Chemistry Or it could be physics Any science or maths course that requires 3-Dimensional unit conversions So what we’re gonna do is, we’re gonna start with The 19.32 g/cm^3 We’re gonna convert it to kg/m^3 So The first factor I’m just gonna take care of are the grams part to convert that over to kg So there’s 1000 grams in 1 kg um Take care of that Now, I’m gonna get rid of the cubic cm’s; Now When you convert cubic cm’s to cubic m’s The, uh, conversion factor for cm’s to m’s is 100 cm in 1m However because it’s a cubic unit By multiplying cm, or dividing by cubic cms You’re only taking out 1 of the 3 units, because that’s cubed So you’d end up with kg/cm^2 uh kg/cm^2 So what you have to do is, you have to do this 3 times Or Just cube this whole factor And what that does is, it not only cubes the cm^3, but it also cubes the m^3 And that takes care of the cm^3 So what we really have is 10^6 and 10^3 of the denominator And overall that’s gonna be 10^3 we’re multiplying by So you get 19,320 kg/m^3 And that’s how you do The Cubic Unit Factor Label Unit Conversions

  1. Thank you. I couldn't for the life of me solve a simple problem that I knew I was doing correctly. I figured out that my calculation for the density of gold was completely wrong. I didn't cube the cm/m. I'm a little rusty.

  2. Dude, seriously awesome video! I spent almost 2 hours looking this up on freaking google and all those people type the answer like we are freaking professors!!! Makes me mad! your video helped me out after watching it once! thanks!

  3. what does this mean though?
    i need help with this:
    Tungsten – Phisycal Properties
    Density (near room temperature)
    19.25 gยทcm^โˆ’3

  4. So do we take 19.32 and use both the conversions to get the answer or just the first one because the second is for the cm3 m3 ?

  5. Erm, excuse my ignorance but, how does the kg/m^3 number turn out bigger than the g/cm^3 number? Isn't g/cm^3 smaller than kg/m^3?.. or is it the other way around?

  6. Dude, like for real here. I'm not playing any games when I say this. But you are a total fucking beast. Thank you and God bless your soul.

  7. If we have size in cm3 of foam mattress example 190*90*10 cm= 171000 then divided it to 20000=8.55 how the 20000 come

  8. Just so……………………………………………………………… boring. My younger sis can solve it easily.

  9. it fucking goes back to the initial value??! if u divide 19.32 by 1000 then multiply it by fucking 1000 ur just going back to 19.32 WHY IS THIS HAPPENING TO ME
