# What is the most appropriate conversion

1. Dec 16, 2007

This is for a Statics course:

Evaluate and express in proper SI units and appropriate prefix:

(200 kN)^2

I did $$(200kN)^2=200^2\cdot 10^3 N\cdot10^3 N= 40\cdot 10^3\cdot 10^6 N^2=40\cdot 10^9 N^2= 40 GN^2$$

Thanks,
Casey

...well it looks correct, although the units would be N^2 and not just N.
