Meters to the -3rd Power: 5.1*10^-5m

[you_of_eh]

What would meters*meters^-3 be?

Ex: 5.1*10^-5m(1.314*10^18m^-4)

[m=meters]

It would be read as "per meter cubed." Number density has this dimension, e.g. "100 molecules per meter cubed."

OK but..

I have to do a calculation multiplying m and m^-3 and I don't know what unit to use for the answer.

Say..5m*5m^-3= 25..what unit?

Also, when you say "per meter cubed", are you talking about m^-3? or m*m^-3?

Thanks for your response.

per meter cubed is 1/m^3, but m*m^-3 is m^-2 or 1/m^2
