For those used to paper weights described in gsm, we have provided the following conversion guide to help understand the kg equivalents. We use the 四六判 shi-roku-ban size paper sheets at Mojoprint as the benchmark. E.g. our 90kg paper corresponds roughly to a 104.7 gsm paper!
We recommend getting your hands on our paper sample book to really get a feel for the weights however.
