Strain Calcs: Convert mm/cm to m?

[alfie254]

Ok, an easy one I think? I am given an equation to work out the strain on a beam, the dimensions of the beam are in the equation (obviously) and in the question these are given in mm and cm, am I right in thinking all the measurements in the equation need to be in m and the question is trying to catch me out?

Thanks

Yes!

(you must get all your measurements into the same system … I assume you're using SI … before you start combining them, or things will go horribly wrong )
