converting unitsIf there are 100cm in a metre then there are 100cmx100cm in 1mx1m and 100cm*100cm*100cm = in a m^3 You question is a little simpler, there are 1000cm^3 in a litre by definition so 1cm is 1/1000 L

No.
1 cm³ = (1 cm) x (1 cm) x (1 cm) = (1 x 10^{2} m) x (1 x 10^{2} m) x (1 x 10^{2} m) = 1 x 10^{6} m³

At the very least, put a space between the two units and put parentheses around the 1. Yours: cm^3s^1 Better: cm^{3} s^{1} or cm^{3} /s
