Conversion

OpenStudy (anonymous):

got the actual conversion from g mm^2 to kg m^2 and its 1.0x10^-9 and im a confused. I got 1x10^-3. I need a step by step solution for this. Thank you

ganeshie8 (ganeshie8):

hey is it `51 g mm^2` or `51 g / mm^2` ?

OpenStudy (anonymous):

51 g * mm^2

ganeshie8 (ganeshie8):

\[\large \rm 51 \cdot ~g~\cdot mm^2 = 51 \cdot \dfrac{1000g}{1000} \cdot mm \times mm\]

ganeshie8 (ganeshie8):

replace 1000g with 1kg

ganeshie8 (ganeshie8):

\[\large \begin{align}\rm 51 \cdot ~g~\cdot mm^2 &= 51 \cdot \dfrac{1000g}{1000} \cdot mm \times mm\\~\\ &=51 \cdot \dfrac{1kg}{1000} \cdot mm \times mm\\~\\ \end{align}\]

OpenStudy (anonymous):

okay so its 0.051mm^2

OpenStudy (anonymous):

got it! my answer is 5.1x10^-8 Thank you

ganeshie8 (ganeshie8):

that looks good!

ganeshie8 (ganeshie8):

\[\large \begin{align}\rm 51 \cdot ~g~\cdot mm^2 &= 51 \cdot \dfrac{1000g}{1000} \cdot mm \times mm\\~\\ &=51 \cdot \dfrac{1kg}{1000} \cdot mm \times mm\\~\\ &=51 \cdot \dfrac{1kg}{1000} \cdot \dfrac{1000 mm}{1000} \times \dfrac{1000 mm}{1000}\\~\\ &=51 \cdot \dfrac{1kg}{1000} \cdot \dfrac{1m}{1000} \times \dfrac{1m}{1000}\\~\\ \end{align}\]

OpenStudy (anonymous):

is there a huge difference between g/mm^2 and g * mm^2?

ganeshie8 (ganeshie8):

yes

ganeshie8 (ganeshie8):

isnt there a huge differene between division and multiplication of you money ? ;p

OpenStudy (anonymous):

hahahahha geez anyway, thank you. hahaha

ganeshie8 (ganeshie8):
