Selling items internationally (especially Europe >UK, UK > Europe) means differentials in relation to sizes & measurements. Imperial and metric measurements are entirely different, and therefore need to be converted or buyers will be totally unclear as to whether the product they are purchasing is the required size.
Not utilizing conversions is likely to impact sales and also increase the rate of return of unwanted products.
As per the above, we convert sizes & measurements on items listed from the UK to Europe and vice versa ie inches to centimetres.
eBay offers a list of specific size conversion guides available here.
WebInterpret also offer our very own tool for Size Conversion, to find out how this works (and it's also available for your Amazon store too) check out this article here.
