Hello there

I dont know how to use the 'metric scales' ruler.

I have to use the scale 1:50 for drafting and the numbers on the rules are in meters.

i've been given the measurements in cm. for example, my stairs raiser is 30 cm.

How do i use the scale ruler? I have to convert cm to m. Please help! I know that 1 m = 100 cm, but why does 30 cm look so small on the paper. it shouldnt be this small!

this is how my ruler looks like : http://www.artsupply.com/alvin/740PM.jpg
