A closer explanation of scales

So now I know the line (in real life) is 3000 cm.

Well, that's quite big - I might do my clever metric conversions here; let's see. 3000 divided by 100 = 30 metres (that's a big line!). I suppose I could convert this to km, but 30 m seems ok. I'll leave it at that.

So let's use the exact same scale we just looked at, but we measure a line on our paper which is 12cm.

So? Well how big/ long is this line in reality?
Well I know that 1cm = 250cm, but there are 12cm on this line, not 1. Ok, I'll simply multiply my 250, twelve times (12 x 250 = 3000)

They can look different, but usually they'll look something like this:

1 : 250
And this means, for every 1 measure (on your paper, or the plan, scale, diagram etc) it's "worth" 250 of the same measure in real life!

We tend to use cm (then we might have to convert later on)

I know it sounds scary, and there are very big numbers involved sometimes, but we can learn to manage them easier than you think...
