# Math Help - How to convert

1. ## How to convert

Hello,
I am stuck on a question on converting. We never took this up in class, so trying to find information on this and have no clue.
I have a number in eng form. 247.84x10^-6 m^4
How do I change it to mm^4??

My brain is on number over load and can't think of it or find the information, thanks.
Joanne

$1\,m=10^3\,mm$, so $1\,m^4=(10^3)^4\,mm=10^{12}\,mm$.

$247.84\cdot 10^{-6}\,m^4=247.84\cdot10^{-6}\cdot10^{12}\,mm=247.84\cdot10^6\,mm$.
