Homework Statement


Essentially I'm working out a problem and im given [tex]\alpha = \frac{15cm\bullet m^{3}}{\mu C} [/tex]
and I need to get it in just terms of meters/coulombs

I'm having a real tough time with weird unit conversions like this.

Homework Equations



1m = 100cm 1 micro coulomb = 1 X 10^-6 coulombs

The Attempt at a Solution


1m/100cm * 10^-6 micro c/1c * the above eq. 1.5 x 10^-7 m^4/C pretty sure that isn't correct.


Thanks

Thanks

the 10^-6 of micro coulomb will become 10^6 when it goes up

bahh >__< i had it right, I guess my problem isn't correct then Thanks everyone

1.5e-7 m^4/C


and whatsthat m^3 with 15cm

no clue why, its from quest hw service and the problem it self is pretty chill, but that one variable is screwing with me.
