Making models to scale

I've got some clay ready and want to make some models.

However, I'm not that good at math so I have no idea how tall they should be. I searched online for a converter but it only gave measurements in inches and I only work in cms.

Perhaps this could be a topic if people aren't quite sure how big their model should be ?

So, does anyone know what 140cms is in cms in 1/24th scale.

The size conversion is 5.8 cms. It is easy to convert just devide the cm's you have by the scale, so in this case 140/24=5.83333333... so I just round off to 5.8.

You take the original size in cm of an animal and this to divide by 24, by a scale of 1:20 to divide by 20, by 1:12 to divide by 12 etc.
I hope I wrote it to understand.

Thank you all :) that makes sense.

This model will be a lot smaller than what I thought
