Why do I need to load samples in mm? 

Loupe is a large, multi-national market network - there are retailers from the USA, the UK, Australia and more. Each of these regions have a different ring size measurement scale. For example, imagine you are selling a ring to retailers in the UK, USA and Germany. The UK, USA and Germany all have different ring size systems.

Instead of having to load the sample 3 times, or declaring the size in every sizing system in the world, Loupe converts the mm size to the retailers selected sizing system. 

So using the example above, a supplier could load one sample with the mm size 16.51 and the UK retailer will see size 'M', the American retailer will see size '6' and the German retailer will see size '16 1/2'.
